4. INSTALLING, COMMISSIONING AND SERVICING

Equipment connections

Personnel undertaking installation, commissioning or servicing work for this
equipment should be aware of the correct working procedures to ensure safety.

The equipment documentation should be consulted before installing,
commissioning, or servicing the equipment.

Terminals exposed during installation, commissioning and maintenance may
present a hazardous voltage unless the equipment is electrically isolated.

The clamping screws of all terminal block connectors, for field wiring, using M4
screws shall be tightened to a nominal torque of 1.3 Nm.

Equipment intended for rack or panel mounting is for use on a flat surface of a
Type 1 enclosure, as defined by Underwriters Laboratories (UL).

Any disassembly of the equipment may expose parts at hazardous voltage, also
electronic parts may be damaged if suitable electrostatic voltage discharge (ESD)
precautions are not taken.

If there is unlocked access to the rear of the equipment, care should be taken by
all personnel to avoid electric shock or energy hazards.

to ensure that terminal block insulation requirements are maintained for safety.

Safety Section P44x/EN SS/H11

(SS) - 5

Watchdog (self-monitoring) contacts are provided in numerical relays to indicate
the health of the device. Alstom Grid strongly recommends that these contacts
are hardwired into the substation's automation system, for alarm purposes.

To ensure that wires are correctly terminated the correct crimp terminal and tool
for the wire size should be used.

The equipment must be connected in accordance with the appropriate connection
diagram.

Protection Class I Equipment

- Before energizing the equipment it must be earthed using the protective
conductor terminal, if provided, or the appropriate termination of the
supply plug in the case of plug connected equipment.

- The protective conductor (earth) connection must not be removed since
the protection against electric shock provided by the equipment would be
lost.

- When the protective (earth) conductor terminal (PCT) is also used to
terminate cable screens, etc., it is essential that the integrity of the
protective (earth) conductor is checked after the addition or removal of
such functional earth connections. For M4 stud PCTs the integrity of the
protective (earth) connections should be ensured by use of a locknut or
similar.

The recommended minimum protective conductor (earth) wire size is 2.5 mm²
(3.3 mm² for North America) unless otherwise stated in the technical data section
of the equipment documentation, or otherwise required by local or country wiring
regulations.

The protective conductor (earth) connection must be low-inductance and as short
as possible.

All connections to the equipment must have a defined potential. Connections that
are pre-wired, but not used, should preferably be grounded when binary inputs
and output relays are isolated. When binary inputs and output relays are
connected to common potential, the pre-wired but unused connections should be
connected to the common potential of the grouped connections.

Before energizing the equipment, the following should be checked:

- Voltage rating/polarity (rating label/equipment documentation);

- CT circuit rating (rating label) and integrity of connections;

- Protective fuse rating;

- Integrity of the protective conductor (earth) connection (where
applicable);

- Voltage and current rating of external wiring, applicable to the application.

Accidental touching of exposed terminals

If working in an area of restricted space, such as a cubicle, where there is a risk of
electric shock due to accidental touching of terminals which do not comply with
IP20 rating, then a suitable protective barrier should be provided.

Equipment use

If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.

Removal of the equipment front panel/cover

Removal of the equipment front panel/cover may expose hazardous live parts,
which must not be touched until the electrical power is removed.

P44x/EN SS/H11 Safety Section

(SS) - 6

UL and CSA/CUL listed or recognized equipment

To maintain UL and CSA/CUL Listing/Recognized status for North America the
equipment should be installed using UL and/or CSA Listed or Recognized parts
for the following items: connection cables, protective fuses/fuseholders or circuit
breakers, insulation crimp terminals, and replacement internal battery, as
specified in the equipment documentation.

For external protective fuses a UL or CSA Listed fuse shall be used. The Listed
type shall be a Class J time delay fuse, with a maximum current rating of 15 A and
a minimum d.c. rating of 250 Vd.c. for example type AJT15.

Where UL or CSA Listing of the equipment is not required, a high rupture capacity
(HRC) fuse type with a maximum current rating of 16 Amps and a minimum d.c.
rating of 250 Vd.c. may be used, for example Red Spot type NIT or TIA.

Equipment operating conditions

The equipment should be operated within the specified electrical and
environmental limits.

Current transformer circuits

Do not open the secondary circuit of a live CT since the high voltage produced
may be lethal to personnel and could damage insulation. Generally, for safety,
the secondary of the line CT must be shorted before opening any connections to
it.

For most equipment with ring-terminal connections, the threaded terminal block
for current transformer termination has automatic CT shorting on removal of the
module. Therefore external shorting of the CTs may not be required, the
equipment documentation should be checked to see if this applies.

For equipment with pin-terminal connections, the threaded terminal block for
current transformer termination does NOT have automatic CT shorting on removal
of the module.

External resistors, including voltage dependent resistors (VDRs)

Where external resistors, including voltage dependent resistors (VDRs), are fitted
to the equipment, these may present a risk of electric shock or burns, if touched.

Battery replacement

Where internal batteries are fitted they should be replaced with the recommended
type and be installed with the correct polarity to avoid possible damage to the
equipment, buildings and persons.

Insulation and dielectric strength testing

Insulation testing may leave capacitors charged up to a hazardous voltage. At the
end of each part of the test, the voltage should be gradually reduced to zero, to
discharge capacitors, before the test leads are disconnected.

Insertion of modules and pcb cards

Modules and PCB cards must not be inserted into or withdrawn from the
equipment whilst it is energized, since this may result in damage.

Insertion and withdrawal of extender cards

Extender cards are available for some equipment. If an extender card is used,
this should not be inserted or withdrawn from the equipment whilst it is energized.
This is to avoid possible shock or damage hazards. Hazardous live voltages may
be accessible on the extender card.

Safety Section P44x/EN SS/H11

External test blocks and test plugs

Great care should be taken when using external test blocks and test plugs such
as the MMLG, MMLB and MiCOM P990 types, hazardous voltages may be
accessible when using these. *CT shorting links must be in place before the
insertion or removal of MMLB test plugs, to avoid potentially lethal voltages.

*Note: When a MiCOM P992 Test Plug is inserted into the MiCOM P991 Test
Block, the secondaries of the line CTs are automatically shorted, making
them safe.

Fiber optic communication

Where fiber optic communication devices are fitted, these should not be viewed
directly. Optical power meters should be used to determine the operation or
signal level of the device.

Cleaning

The equipment may be cleaned using a lint free cloth dampened with clean water,
when no connections are energized. Contact fingers of test plugs are normally
protected by petroleum jelly, which should not be removed.

(SS) - 7

5. DE-COMMISSIONING AND DISPOSAL

De-commissioning

The supply input (auxiliary) for the equipment may include capacitors across the
supply or to earth. To avoid electric shock or energy hazards, after completely
isolating the supplies to the equipment (both poles of any dc supply), the
capacitors should be safely discharged via the external terminals prior to
de-commissioning.

Disposal

It is recommended that incineration and disposal to water courses is avoided.
The equipment should be disposed of in a safe manner. Any equipment
containing batteries should have them removed before disposal, taking
precautions to avoid short circuits. Particular regulations within the country of
operation, may apply to the disposal of the equipment.

6. TECHNICAL SPECIFICATIONS FOR SAFETY

Unless otherwise stated in the equipment technical manual, the following data is applicable.

6.1 Protective fuse rating

The

recommended maximum rating of the external protective fuse for equipments is 16A,
high rupture capacity (HRC) Red Spot type NIT, or TIA, or equivalent. The protective fuse
should be located as close to the unit as possible.

DANGER - CTs must NOT be fused since open circuiting them may
produce lethal hazardous voltages.

3 PRODUCT SCOPE

The MiCOM P442 and P444 Numerical Full Scheme Distance Relays provide
comprehensive distance protection for different applications like: lines, cables, tapped lines,
lines with multiple zero sequence sources, non-homogeneous lines, series compensated
lines and parallel lines.

The independently settable resistive reach for e ach zone allows easy application to short
lines and cable protection. Using well-proven, patented techniques to directionalise, and
making full use of digital memory, the relays can be appl i ed i n situations that can cause
classic distance implementations to maloperat e (crosscountry faults and close-up faults).

The MiCOM P442 and P444 are in-built with a library of channel aided scheme logic,
supplementary and back-up protection. It prov ides complete protection (4 alternative setting
groups) to solidly earthed systems from distribut ion t o transmission voltage levels.

Three phase tripping with faulted phase indication is provided for all protection functions. In
addition models P442 and P444 allow single-pha se t ripping for the distance protection and
the channel aided DEF protection (67N).

The P442 and P444 distance relays equipped with 150 MHz CPU and coprocessor board
have been enhanced as described in the following table:

1 GETTING STARTED

Before carrying out any work on the equipment, the user should be familiar with the

1.1 User interfaces and menu structure

1.2 Introduction to the relay

1.2.1 Front panel

contents of the Safety Section/Safety Guide Pxxx-SG-4L-2 or later issue, the Technical
Data chapter and the ratings on the equipment rating label.

The settings and functions of the MiCOM protection relay can be accessed both from the
front panel keypad and LCD, and via the front and rear co m m unication ports. Information on
each of these methods is given in this section to describe how to get started using the relay.

The front panel of the relay is shown in the following figures, with the hinged covers at the
top and bottom of the relay shown open. Extra phy sic al prot ection for the front panel can be
provided by an optional transparent front cover. With the cover in place read only access to
the user interface is possible. Removal of the cov er does not compromise the environmental
withstand capability of the product, but allows ac cess to the relay settings. When full access
to the relay keypad is required, to edit the setting s, the transparent cover can be unclipped
and removed when the top and bottom covers are ope n. If the lower cover is secured with a
wire seal, this will need to be removed. Using the side flanges of the transparent cover, pull
the bottom edge away from the relay front panel unti l i t is clear of the seal tab.

The cover can then be moved vertically down to release t he t wo fixing lugs from their
recesses in the front panel.

Figure 1: MiCOM P442 & P444 Relay front view (HARDWARE M)

The front panel of the relay includes the following:

• a 16-character by 2- or 3-line (alphanumeric liquid crystal display (LCD).

• a keypad comprising 4 arrow keys ( , ,  and ), an enter key (), a clear key

(), and a read key () and two additive hotkeys.

• 12 LEDs; 4 fixed function LEDs on the left hand side of the front panel and 8
programmable function LEDs on the right hand side.

• 10 additional function keys plus 10 additional LEDs .

Hotkey functionality (Figure 1):

• SCROLL: Starts scrolling through the various default displays.

• STOP: Stops scrolling the default display

for control of setting groups, control inputs and circuit breaker operation.
Function key functionality (Figure 1):

• The relay front panel, features control pushbutton switches with programmabl e LE Ds
that facilitate local control. Factory default set tings associate specific relay functions
with these 10 direct-action pushbuttons and LEDs e.g. Enable/Disable the auto­recloser function. Using programmable scheme lo gi c, the user can readily change the
default direct-action pushbutton functions and LED indications to fit specific control
and operational needs.

Under the top hinged cover:

• the relay serial number, and the relay’s current and voltage rating informatio n* .

Under the bottom hinged cover:

• battery compartment to hold the ½ AA size battery which is used for memo ry
back-up for the real time clock, event, fault and disturbance records.

• a 9-pin female D-type front port for communication with a PC locally to t he relay
(distance of up to 15m) via an EIA(RS)232 serial data connecti on.

• a 25-pin female D-type port providing internal signal monitoring and high speed local
downloading of software and language text via a parallel data connection.

The fixed function LEDs on the left hand side of the front panel are used to indicate the
following conditions:

• Trip (Red) indicates that the relay has issued a trip signal. It is reset when the
associated fault record is cleared from the front display. (Alternatively the trip LED can
be configured to be self-resetting)*.

• Alarm (Yellow) flashes to indicate that the relay has registered an alarm. Thi s may be
triggered by a fault, event or maintenance record. The LED will flash until the alarms
have been accepted (read), after which the LED will change to constant illumination,
and will extinguish when the alarms have been clear ed.

• Out of service (Yellow) indicates that the relay’s protection is unavail abl e.

• Healthy (Green) indicates that the relay is in correct working order, and shoul d be on

at all times. It will be extinguished if the relay’s self -t est facilities indicate that there is
an error in the relay’s hardware or software. The state of the healthy LED is reflected
by the watchdog contact at the back of the relay.

To improve the visibility of the settings via the front panel, the LCD contrast can be adjusted
using the “LCD Contrast” setting with the last cell in the CONFIGURATION column.

1.2.2 Relay rear panel The rear panel of the relay is shown in Figure 2 (refer to section P44x/EN IN ‘Installation’ for

terminals connections layout). All current and voltage signals, digital logic input signals and
output contacts are connected at the rear of the relay. Also connected at the rear is the
twisted pair wiring for the rear EIA(RS)485 communi cation port, the IRIG-B time
synchronising input and the optical fibre rear comm unication port which are both optional. A
second rear port (Courier) and an interMiCOM port are also available.

1.3 Relay connection and power-up

Before powering-up the relay, confirm that t he relay power supply voltage and nominal ac
signal magnitudes are appropriate for your applicat i on. The relay serial number, and the
relay’s current and voltage rating, power rating information can be viewed under the top
hinged cover. The relay is available in the following auxiliary voltage versions and these are
specified in the table below:

Nominal Ranges

24 – 48 V dc 19 to 65 V ­48 – 110 V dc (30 – 100 V ac rms) ** 37 to 150 V 24 to 110 V
110 – 250 V dc (100 – 240 V ac rms) ** 87 to 300 V 80 to 265 V

** rated for ac or dc operation
Please note that the label does not specify the l ogic input ratings. The P44x relays are fitted

with universal opto isolated logic inputs that can be programmed for the nominal battery
voltage of the circuit of which they are a part. See ‘Universal Opto input’ in the Firmware
section for more information on logic input specif i cati ons. Please note that the opto inputs
have a maximum input voltage rating of 300 V dc at any setting.

Once the ratings have been verified for the application, connect external power capable of
delivering the power requirements specified on t he l abel to perform the relay familiarization
procedures. Figure 1 and 2 indicates the location of the power supply terminals but please
refer to the wiring diagrams in the Installation section for complete installation details
ensuring that the correct polarities are observe d i n the case of dc supply.

1.4 Introduction to the user interfaces and settings options

The relay has thre following interfaces:

• the front panel user interface via t he LCD and keypad.

Operative dc

• the front port which supports Courier communication.

• the rear port which supports one protocol of either Courier, Modbus,

IEC 60870-5-103 or DNP3.0. The protocol for the rea r port must be specified when t

elay is ordered.

r

• the optional Ethernet, dual Ethernet or 9-2 Ethernet port(s),

• The optional second rear port which supports Courier protocol.

The measurement information and relay settings which can be accessed from the three
interfaces are summarised in Table 1.

1.5 Menu structure

The relay’s menu is arranged in a tabular structure. Each setting in the menu is referred to
as a cell, and each cell in the menu may be accessed by ref erence to a row and column
address. The settings are arranged so that each colu m n cont ains related settings, for
example all of the disturbance recorder settings are contained within the same column. As
shown in Figure 3, the top row of each column contains the heading which describes the
settings contained within that column. Movement between the columns of the menu is only
possible at the column heading level. A complete li st of all of the menu settings is given in
the manual.

Figure 3: Menu structure

All of the settings in the menu fall into one of three categories: protection settings,
disturbance recorder settings, or control and support (C&S) settings. One of two different
methods is used to change a setting depending on w hi ch category the setting falls into.
Control and support settings are stored and used by the relay immediately after they are
entered. For either protection settings or disturbance recorder settings, the relay stores the
new setting values in a temporary ‘scratchpad’. It activates all the new settings together, but
only after it has been confirmed that the new sett i ngs are to be adopted. This technique is
employed to provide extra security, and so that several setting changes that are made within
a group of protection settings will all take effect at the same time.

1.5.1 Protection settings The protection settings include the following item s:

• protection element settings

• scheme logic settings

• auto-reclose and check synchronisation settings (where appropriate)*

• fault locator settings (where appropriate)*

There are four groups of protection settings, with e ach group containing the same setting
cells. One group of protection settings is selected a s t he acti ve group, and is used by the
protection elements.

1.5.2 Disturbance recorder settings The disturbance recorder settings include the re cord duration and trigger position, selection

of analogue and digital signals to record, and the signal sources that trigger the recording.

1.5.3 Control and support settings The control and support settings include:

• relay configuration settings

• open/close circuit breaker*

1.6 Password protection

The menu structure contains three (general) or four (models with Cyber security features)
levels of access. The level of access that is enabled determines which of the relay’s settings
can be changed and is controlled by entry of two dif ferent passwords. The levels of access
are summarised in Tables 2 or 3.

Table 3 – Level of access: Relays with Cyber Security features

Level management, including password descript i on, management and recovery, is fully
described in section P746/EN CS (relays with Cyber Security features).

Each of the passwords is 4 (or 8) characters of upper case text. The factory default for both
passwords is AAAA (General case). For models with Cyber Security features: default
passwords are blank for Level 1, BBBB for level 2 and AAAA for Level 3. Each password is
user-changeable once it has been correctly entered. Entry of t he pass word is achieved either
by a prompt when a setting change is attempted, or by moving to the ‘Password’ cell in the
‘System data’ column of the menu. The level of acc ess is independently enabled for each
interface, that is to say if level 2 access is enabled for the rear communication port, the front
panel access will remain at level 0 unless the relevant password is entered at the front panel.
The access level enabled by the password entry will t i m e-out independently for each
interface after a period of inactivity and revert to t he default level. If the passwords are lost
an emergency password can be supplied by contacting General Electric with the relay’s
serial number and security code (relays with Cyber Security features). The current level of
access enabled for an interface can be determined by examining the 'Access level' cell in the
'System data' column, the access level for the front panel User Interface (UI), can also be
found as one of the default display options.

The relay is supplied with a default access level of 2 or 3, such that no password is required
to change any of the relay settings. It is also possible to set the default menu access level to
either level 0 or level 1, preventing write access to t he relay settings without the correct
password. The default menu access level is set in the ‘Password control’ cell that is found in
the ‘System data’ column of the menu (note that t hi s s etting can only be changed when level
2 access is enabled).

1.7 Relay configuration

The relay is a multi-function device that supports num erous different protection, control and
communication features. In order to simplify t he set t ing of the relay, there is a configuration
settings column that can be used to enable or disable many of the functions of the relay. The
settings associated with any function that is disabled are made invisible, i.e. they are not
shown in the menu. To disable a function change the relevant cell in the ‘Configuration’
column from ‘Enabled’ to ‘Disabled’.

The configuration column controls which of the four protection settings groups is selected as
active through the ‘Active settings’ cell. A prot ecti on setting group can also be disabled in the

Getting Started

P44x/EN GS/Hb6

MiCOM P40 Agile P442, P444

13

(GS) 3-

configuration column, provided it is not the present active group. Similarly, a disabled setting
group cannot be set as the active group.

The column also allows all of the setting values in one group of protection settings to be
copied to another group.

To do this firstly set the ‘Copy from’ cell to the protecti on set t i ng group to be copied, then set
the ‘Copy to’ cell to the protection group where the copy is to be placed. The copied settings
are initially placed in the temporary scratchpad, and will only be used by the relay following
confirmation.

To restore the default values to the settings in any protection settings group, set the ‘Restore
defaults’ cell to the relevant group number. Alternatively it is possible to set the ‘Restore
defaults’ cell to ‘All settings’ to restore the default v al ues to all of the relay’s settings, not just
the protection groups’ settings. The default settings will initially be placed in the scratchpad
and will only be used by the relay after they have been confir m ed. Note that restoring
defaults to all settings includes the rear communicat i on port settings, which may result in
communication via the rear port being disrupted if the new (default) settings do not match
those of the master station.

1.8 Front panel user interface (keypad and LCD)

When the keypad is exposed it provides full access to the menu options of the relay, with the
information displayed on the LCD.

The , ,  and  keys which are used for menu navigation a nd setting value changes
include an auto-repeat function that comes into op eration if any of these keys are held
continually pressed. This can be used to speed up both setting value changes and menu
navigation; the longer the key is held depressed, t he faster the rate of change or movement
becomes.

1.8.1 Default display and menu time-out The front panel menu has a selectable default displ ay. The relay will time-out and return to

the default display and turn the LCD backlight off after 15 minutes of keypad inactivity. If this
happens any setting changes which have not been confirmed will be lost and the original
setting values maintained.

Figure 5: Default display navigation

The right cursor key takes you to the next menu option in a clockwise direction, whereas the
left cursor key takes you to the next menu option in an anti-clockwise direction.

If the device is not yet configured for NERC compliance (see cyber Security chapter) a
warning will appear when moving from the "NER C compliant" banner. The warning message
is as follows:

DISPLAY NOT NERC

COMPLIANT. OK?

You will have to confirm with the ENTER button before you can go any further.

Note: The unit is delivered with the NERC-compliant default display. Please see the Cyber

Security chapter for further details

Note: Whenever the unit has an uncleared alarm the default display is replaced by the text

Alarms/ Faults present. You cannot override this default display. Howev er, you can
enter the menu structure from the def ault display, even if the display shows the
Alarms/Faults present message.

1.8.2 Menu navigation and setting browsing The menu can be browsed using the four arrow keys, foll owing the structure shown in Figure

4. Therefore, starting at the default display the  key will di splay the first column heading.
To select the required column heading use the  and  keys. The setting data contained in
the column can then be viewed by using the  and  keys. It is possible to return to the
column header either by holding the  key down or by a single press of the clear key . It
is only possible to move across columns at the column heading level. To return to the default
display press the  key or the clear key  from any of the column headings. It is not
possible to go straight to the default display from within one of the column cells using the
auto-repeat facility of the  key, as the auto-repeat will stop at the column heading. To
move to the default display, the  key must be released and pressed again.

display the direct access key below the “HOTKEY” text must be pressed. Once in the hotkey
menu the  and  keys can be used to scroll between the available options and the direct
access keys can be used to control the function currently displayed. If neither the  or 
keys are pressed with 20 seconds of entering a hotkey sub menu, the relay will revert to the
default display. The clear key  will also act t o ret urn to the default menu from any page of
the hotkey menu. The layout of a typical page of the hotkey m enu is described below:

• The top line shows the contents of the previous and next cells for easy menu
navigation.

• The centre line shows the function.

• The bottom line shows the options assigned to the direct access keys.

The functions available in the hotkey menu are listed bel ow:

1.8.3.1 Setting group selection The user can either scroll using <<NXT GRP>> thr ough the available setting groups or

<<SELECT>> the setting group that is currently di splayed.
When the SELECT button is pressed a screen confi rming the current setting group is

displayed for 2 seconds before the user is prompted with the <<NXT GRP>> or
<<SELECT>> options again. The user can exit the sub menu by using the left and right
arrow keys.

For more information on setting group selection ref er to “Changing setting group” section in
the Setting section (P44x/EN ST).

1.8.3.2 Control inputs – user assignable functions The number of control inputs (user assignable funct ions – USR ASS) represented in the

hotkey menu is user configurable in the “CTRL I/P CONFI G” column. The chosen inputs can
be SET/RESET using the hotkey menu.

For more information refer to the “Control Input s” section in the Setting section
(P44x/EN ST).

1.8.3.3 CB control The CB control functionality varies from one Px40 relay to another. For a detailed

description of the CB control via the hotkey menu refer to the “Circuit breaker control” section
of the Setting section (P44x/EN ST).

1.8.4 Password entry

1.8.4.1 Standard relays When entry of a password is required the following prompt will appear:

Enter password
**** Level 1

Note: The password required to edit the setting is the prompt as shown above.

A flashing cursor will indicate which character field of the password may be changed. Press
the  and  keys to vary each character between A and Z . To move between the
character fields of the password, use the  and  keys. The password is confirmed by
pressing the enter key . The display will revert to ‘Enter Password’ if an incorrect
password is entered. At this point a message will be d i splayed indicating whether a correct
password has been entered and if so what level of access has been unlocked. If this level is
sufficient to edit the selected setting then the display will return to the set ting page to allow
the edit to continue. If the correct level of password has not been entered then the password
prompt page will be returned to. To escape from this prompt press the clear key .
Alternatively, the password can be entered usi ng the ‘Password’ cell of the ‘System data’
column.

1.8.4.2 Relays with Cyber Security

For the front panel user interface the password protected access will revert to the default
access level after a keypad inactivity time-out of 15 m i nutes. It is possible to manually reset
the password protection to the default level by moving to the ‘Password’ menu cell in the
‘System data’ column and pressing the clear key  instead of entering a password.

Configuring the default display (in addition to m odification of other settings) requires level 3
access. You will be prompted for a password before y ou can make any changes, as follows.
The default level 3 password is AAAA.

Enter Password

1. A flashing cursor shows which character field of the password can be changed. Press
the up or down cursor keys to change each character ( tip: pressing the up arrow once
will return an upper case "A" as required by the default level 3 password).

2. Use the left and right cursor keys to move between the character fields of the
password.

3. Press the Enter key to confirm the password. If you enter an incorrect password, an
invalid password message is displayed then the display reverts to Enter password.
Upon entering a valid password a message appears indicating that the password is
correct and if so what level of access has been unlocked. If this level is sufficient to
edit the selected setting, the display returns to the setting page to allow the edit to
continue. If the correct level of password has not be en entered, the password prompt
page appears again.

4. To escape from this prompt press the Clear key. Alternatively, enter the password
using System data > Password. If the keypad is in active for 15 minutes, the password
protection of the front panel user interface reverts to the default access level.

5. To manually reset the password protection to the default level, select System data >
Password, then press the clear key instead of entering a password.

1.8.5 Reading and clearing of alarm messages and fault records The presence of one or more alarm messages will be indicated by the default display and by

the yellow alarm LED flashing. The alarm messag es can either be self-resetting or latched,
in which case they must be cleared manually . To view the alarm messages press the read
key . When all alarms have been viewed, but not cleared, t he alarm LED will change from
flashing to constant illumination and the latest faul t record will be displayed (if there is one).
To scroll through the pages of this use the  key. When all pages of the fault record have
been viewed, the following prompt will appear:

Press clear to
reset alarms

To clear all alarm messages press ; to return to the alarms/faults present display and
leave the alarms uncleared, press . Depending on the password configuration settings, it
may be necessary to enter a password before the ala rm messages can be cleared (see
section on password entry). When the alarms hav e been cleared the yellow alarm LED will
extinguish, as will the red trip LED if it was illuminated following a trip.

Alternatively it is possible to accelerate the procedure, once the alarm viewer has been
entered using the  key, the  key can be pressed and this will move the display straight
to the fault record. Pressing  again will move straight to the alarm reset prompt where
pressing  once more will clear all alarms.

1.8.6 Setting changes To change the value of a setting, first navigate the menu to display the relevant cell. To

change the cell value press the enter key  which will bring up a flashing cursor on t he LCD
to indicate that the value can be changed. This will only happen if the appropriate password
has been entered, otherwise the prompt to enter a password will appear. The setting value
can then be changed by pressing the  or  keys. If the set t i ng to be changed is a binary
value or a text string, the required bit or character to be cha nged must first be selected using
the  and  keys. When the desired new value has been reached it is confirmed as the new
setting value by pressing . Alternatively, the new value will be discarded either if the clear
button  is pressed or if the menu time-out occurs.

For protection group settings and disturbance recorder settings, the changes must be
confirmed before they are used by the relay. To do this, when all required changes have
been entered, return to the column heading level and press the key. Prior to returning to the
default display the following prompt will be given:

Pressing  will result in the new settings being adopted, pressing  will cause the relay to
discard the newly entered values. It should be noted that, the setting values will also be
discarded if the menu time out occurs before the sett i ng changes have been confirmed.
Control and support settings will be updated immedi ately after they are entered, without
‘Update settings?’ prompt.

1.9 Front communication port user interface

The front communication port is provided by a 9-pin f emale D-type connector located under
the bottom hinged cover. It provides EIA(RS)232 serial data communication and is intended
for use with a PC locally to the relay (up to 15m distan ce) as shown in Figure 7. This port
supports the Courier communication protocol only. Courier is the communication language
developed by Alstom Grid to allow communication with its range of protection relays. The
front port is particularly designed for use with the relay settings program MiCOM S1 a
Windows 95/NT based software package.

Figure 7: Front port connection

The relay is a Data Communication Equipment ( DCE) device. Therefore the pin connections
of the relay’s 9-pin front port are as follows:

Pin no. 2 Tx Transmit data
Pin no. 3 Rx Receive data
Pin no. 5 0V Zero volts common
None of the other pins are connected in the relay. The relay should be connected to the

serial port of a PC, usually called COM1 or COM2. PCs a re normally Data Terminal
Equipment (DTE) devices that have a serial po rt pi n connection as below (if in doubt check
your PC manual):

25 Way 9 Way
Pin no. 3 2 Rx Receive data
Pin no. 2 3 Tx Transmit data
Pin no. 7 5 0V Zero volts common

For successful data communication, the Tx pi n on t he relay must be connected to the Rx pin
on the PC, and the Rx pin on the relay must be connected to the Tx pin on the PC, as shown
in Figure 8. Therefore, providing that the PC is a DTE with pin connections as given above, a
‘straight through’ serial connector is required, i. e. one that connects pin 2 to pin 2, pin 3 to
pin 3, and pin 5 to pin 5. Note that a common cause of dif ficulty with serial data

P44x/EN GS/Hb6

Getting Started

(GS) 3

MiCOM P40 Agile P442, P444

P 01 08 EN d

-20

communication is connecting Tx to Tx and Rx to Rx. T hi s could happen if a ‘cross-over’
serial connector is used, i.e. one that connects pin 2 to pin 3, and pin 3 to pin 2, or if the PC
has the same pin configuration as the relay.

Figure 8: PC – relay signal connection

Having made the physical connection from the relay to the PC, the PC’s communication
settings must be configured to match those of the rel ay. The relay’s communication settings
for the front port are fixed as shown in the table below:

Protocol Courier
Baud rate 19,200 bits/s
Courier address 1
Message format 11 bit - 1 start bit, 8 data bits, 1 parity bit (even parity), 1 stop bit

The inactivity timer for the front port is set at 15 minut es. T his controls how long the relay will
maintain its level of password access on the front port. If no messages are received on the
front port for 15 minutes then any password access le vel that has been enabled will be
revoked.

1.10 Introduction to the Settings Application Software

The settings application software used in this ran ge of IEDs is called MiCOM S1 Agile. It is a
collection of software tools, which is used for mana gi ng all aspects of the IEDs. This chapter
provides a brief summary of each software tool. Further information is available in the Help
system and in the Settings Application Software Guid e P40-M&CR-UG-EN-n, where n is the
latest version of the settings application software.

The software allows you to edit device settings and co m m ands for General Electric’s range
of IEDs. It is compatible with Windows XP, Windows Vista and Windows 7 operat i ng
systems.

It also enables you to manage the MiCOM devices i n your system. You can build a list of
devices and organize them in the same way as they physically exist in a system. Parameters
can be created and uploaded for each device, and devices can be supervised directly.

It also includes a Product Selector tool. This is an interactive product catalogue, which
makes it easier to choose the right device for each ap pl icat i on.

1.10.1 Getting Started
S1 Agile allows you to create a model of a protection sy stem which simulates a real-world

protection system. You can add substations, bay s, voltage levels and devices to the system.
First you need to download the data models for the devices in the system. Then you can
either create a new system or open an existing system. You can connect to an IED either
directly through the front port or to an IED in the syste m m odel . You can then send or extract
settings. You can also extract PSL, DNP3, Events or Disturbance Record files.

If there is no default system, use Quick Connect to automatically create one. If a system is
no longer needed, right-click it and select Delet e to permanently delete it. Systems are not
opened automatically. To change this, select Options then Preferences then check the
checkbox Reopen last System at start-up.

1.10.2 PSL editor The Programmable Scheme Logic (PSL) is a module of programmable logic gates and

timers in the IED, which can be used to create custom ised internal logic. This is done by
combining the IED's digital inputs with internally generated digital signals using logic gates
and timers, then mapping the resultant signals to the IED's digital outputs and LEDs.

The Programmable Scheme Logic (PSL) Editor allow s you to create and edit scheme logic
diagrams to suit your own particular application.

1.10.3 IEC 61850 Configurator IEC 61850 is a substation communications standard. It standardizes the way data is

transferred to and from IEC 61850 compliant I E Ds, making the communication independent
of the manufacturer. This makes it easier to conne ct different manufacturers’ products
together and simplifies wiring and network chan ges.

The IEC 61850 Configurator tool is used to configure the IEC 61850 settings of MiCOM
IEDs, not the protection settings. It also allows you to extract a configuration file so you can
view, check and modify the IEC 61850 settings during prec om m issioning.

1.10.4 DNP3 configurator DNP3 (Distributed Network Protocol) is a master/ slave protocol developed for reliable

communications
between various types of data acquisition and contr ol equipment. It allows interoperability

between various SCADA components in substati ons. It was designed to function with
adverse electrical conditions such as electromagnetic distortion, aging components and poor
transmission media.

The DNP3 Configurator allows you to retrieve and edi t its settings and send the modified file
back to a MiCOM IED.

1.10.5 S&R courier Settings and Records - Courier enables you to connect to any Courier device, retrieve and

edit its settings and send the modified settings back to a Courier device, including DNP 3.0
configuration if supported by the device.

Although each device has different settings, each cell is presented in a uniform style,
showing the permissible range and step size allowe d.

Settings and Records - Courier also enables you to:

• extract events from a device

P44x/EN GS/Hb6

(GS) 3

-24

MiCOM P40 Agile P442, P444

• extract disturbance records from a device

• control breakers and isolators

• set the date and time on a device

• set the active group on a device

• change the address of a device

• save settings, DNP 3.0 configuration, events and disturbance files to disk

1.10.6 AEDR2 AutoExtract Disturbance Records 2 (AEDR2) autom at i call y reads COMTRADE disturbance

records from the rear communication ports of both K-Series and MiCOM Px40 devices with
the Courier protocol, and from Px40 devices with the IEC 60870-5-103 protocol.

AEDR2 is configured with an initialisation file. This file contains all settings, file names and
file directories needed for configuration. This file can be created and edit ed using a standard
text editor. Log files are also defined in the initial isat i on file which are used by AEDR2 to
record a history of events and errors.

Once configured, disturbance records are automat i cally extracted according to a schedule
from devices connected in a defined range of addr esses. This is done using the Windows®
Scheduled Task facility which can be used to execute one or seve ral schedules. All new
disturbance records are saved to a user-defined drive and filename.

AEDR2 also has a test function to ensure the initialisa t i on file has been properly configured.
The command line is used to execute the test function and validate the initialisation file. The
command line can also be used to manually execute the AEDR2 application on demand.

WinAEDR2 is a management facility for AEDR2. It shows the history of all previous
extractions and has shortcut buttons to launch WaveWin, Windows Explorer and the
Scheduled Task facility. It can also be used to vi ew log files, and edit and test the
initialisation file.

1.10.7 WinAEDR2 WinAEDR2 is a management facility for AEDR2. It shows the history of all previous

extractions and has shortcut buttons to launch Wav eWin, Windows Explorer and the
Scheduled Task facility. It can also be used to vi ew log files, and edit and test the
initialisation file.

1.10.8 Wavewin Wavewin is used for viewing and analysing waveforms from disturbance records. It can be

used to determine the sequence of events that l ed to a fault.
Wavewin provides the following functions:

• File management

• Query management

• Log management

1.10.9 Device (Menu) Text Editor

• Report generation

• Sequence of Events(SOE)

• Conversion of COMTRADE files

• Waveform summary

The Menu Text Editor enables you to modify and replace t he m enu texts held in MiCOM
Px4x IEDs. For example, you may want to customise an IED so that menus appear in a
language other than one of the standard languages.

(GS) 3-

By loading a copy of the current menu text file in one of the standard languages into the
reference column, you can type the appropriate translation of each menu entry into the target
column.

This can then be sent from the PC to the IED, replacing one of the current standard
languages. New menu text files created this way can also be saved to disk for later use or
further editing.

1.10.10 Event viewer IEDs record all events in an event log. This allows you to establish the sequence of events

that led up to a particular situation. For example, a change in a digital input signal or
protection element output signal would cause an event record to be created and stored in the
event log. This could be used to analyse how a particular power system condition was
caused.

When available space is exhausted, the oldest event is overwritten by the new one. The
IED's internal clock provides a time tag for each event.

The event records can be displayed on an IED's front panel but it is easier to view them
through the settings application software. Thi s c an extract the events log from the device and
store it as a single .evt file for analysis on a PC.

1.2 Configuration column (“Configuration” menu)

The relay is a multi-function device that supports numerous different protection, control and
communication features. To simplify the sett i ng of the relay, there is a configuration settings
column which can be used to enable or disable many of t he functions of the relay. The
settings associated with any function that is disabled are made invisible; i.e. they are not
shown in the menu. To disable a function change the relevant cell in the Configuration
column from Enabled to Disabled.

P44x/EN ST/Hb

Setting Range

Step Size

Min. Max.

The configuration column controls which of t he four protection settings groups are selected
as active through the ‘Active settings’ cell. A prot ect i on setting group can also be disabled in
the configuration column, provided it is not the present active group. Similarly, a disabled
setting group cannot be set as the active group.

The column also allows all of the setting values in one group of protection settings to be
copied to another group.

Set the Copy from cell to the protection setting group t o be copied, then set the Copy to cell
to the protection group where the copy is to be placed. The copied settings are placed in the
temporary scratchpad and are only used following confirmation.

1.2.1 Alternative setting groups The P442 and P444 relays can store up to four independent groups of settings. The active

group is selected either locally using the menu or remotely using the serial communications.
The ability to quickly reconfigure the relay to a new setting group may be desirable if
changes to the system configuration demand new p rotection settings. Typical examples
where this feature can be used include:

Single-bus installations with a transfer bus;
Double bus installations, with or without a separate transfer bus, where the transfer circuit

breaker or bus coupler might be used to take up the dut i es of any feeder circuit breaker
when both the feeder circuit breaker and the cur rent t ransformers are by-passed.

For a double bus installation, it is usual for bus 1 to be ref erred to as the main bus and bus 2
as the reserve bus, and for any bypass circuit isolat or to be connected to bus 2 as shown in
Figure 1. This arrangement avoids the need for a cur rent polarity reversing switch that would
be required if both buses were to be used for by-pass purposes. The standby relay,
associated with the transfer circuit breaker or the bus coupler, can be programmed with the
individual setting required for each of the outgoing feeders. For bypass operation the

appropriate setting group can be selected as required. This facility is extremely useful in the
case of unattended substations where all of the switching can be controlled remotely.

P44x/EN ST/Hb

Figure 1 - Typical Double Bus Installation with Bypass Facilities

A further use for this feature is the ability to provide alternative settings for teed feeders or
double circuit lines with mutual coupling. Simi lar al t ernative settings could be required to
cover different operating criteria in the event of the channel failing, or an alternative system
configuration (ie. lines being switched in or out).

1.2.2 Selection of Setting Groups Setting groups can be changed by one of two methods:

Automatic group selection by state changes of two opto-isolated inputs, assigned to Setting
Group Change bit 0 (opto 1), and Setting Group Change bit 1 (opto 2), as shown in Table 1
below. The new setting group binary code must be maintained for 2 seconds before a group
change is implemented, therefore rejecting spurious induced interference. (See also
hysteresis value for logic level 0 & logic level 1 in secti on 4.1 of this document).
When this selection is made, the two opto-isolated inputs assigned to this function are opto
inputs 1 and 2 and they must not be connected to any output signal in the PSL.
Special care should be taken to avoid using them for another purp ose (i.e please note that in
the default PSL they have been used for another functions: DIST/DEF Chan. Recv. for opto
1 and DIST/DEF carrier out of service for opto 2).

Default PSL: To enable the setting group via logic inputs, the opto inputs 1 and 2 must be
dedicated only to the group selection (remove Opto-Label 01 and Opto-Label 02 from the
PSL). (If assigned in the PSL, instead of Dist DEF Carrier Receive Logic Start, a setting
group change occurs)

Note that each setting group has its own dedicated PSL, which should be configured and
sent to the relay independently.

Or using the relay operator interface / remote comm unications. Should the user issue a
menu command to change group, the relay transfers to that settings group, and then ignores
future changes in state of the bit 0 and bit 1 opto input s. Therefore, the user is given greater
priority than automatic setting group selection.

2.2 Distance protection schemes (“Distance Scheme” menu)

The option of using separate channels for Directional Earth Fault (DEF) aided tripping, and
distance protection schemes, is offered in t he P442 and P444 relays. Alternatively, the aided
DEF protection can share the distance protection signalling channel, and the same scheme
logic. In this case, a permissive overreach or blocking distance scheme must be used. The
aided tripping schemes can perform single pole tripping. The relays include basic five-zone
distance scheme logic for stand-alone operation (where no signalling channel is available)
and logic for a number of optional additional schemes. The features of the basic scheme are
available even if an additional scheme has been selected or not.

The function is based on a specification with a dedicated application equivalent to a
customised weak infeed.

2.3 Power Swing detection and blocking (PSB) (“Power swing” menu)

Power swings are oscillations in the power flow after a power system disturbance, caused by
sudden removal of faults, loss of synchronism or power flow direction changing (as a result
of switching). Such disturbances can cause generators acceleration or deceleration adapted
to power flow, which in turn leads to power swinging.

A power swing may cause the impedance presented t o a di st ance relay to move away from
the normal load area and into one or more of its tripping ch aracteristics. Depending on the
setting or power swing stability, the relay should trip or not.

The overcurrent protection included in the P442 and P 444 relays provides two stage non­directional / directional three-phase overcurrent protection and two non-directional stages
(I>3 and I>4), with independent time-delay characteristics. One or more stages may be
enabled to complement the relay distance protection. All overcurrent and directional settings
apply to all three-phases but are independent for each of the four stages. The first two
stages of overcurrent protection, I>1 and I>2 have time-delayed ch aracteristics that are
selectable between inverse definite minimum t i me (I DMT), or definite time (DT).

All the stages trip three-phase only. They could be us ed for back up protection during a VT
failure.

2.5 Negative sequence overcurrent protection (“NEG sequence O/C” menu)

When applying traditional phase overcurrent protection, the overcurrent elements must be
set higher than maximum load current, thereby limiting the element’s sensitivity. Most
protection schemes also use an earth fault element operating from residual current, which

Setting

P442, P444 (ST) 4-

improves sensitivity for earth faults. However, certain fault s may arise which can remain
undetected by such schemes.

Any unbalanced fault condition will produce negat i ve sequence current of some magnitude.
Therefore, a negative phase sequence overcurrent element can operate for both phase-to­phase and phase to earth faults.

The following section describes how negative pha se sequence overcurrent protection may
be applied in conjunction with standard overcurrent and earth fault protection to alleviate
some less common application difficulties.

• Negative phase sequence overcurrent elements give greater sensitivity to resistive
phase-to-phase faults, where phase overcurrent el em ents may not operate.

• In certain applications, residual current may not be detected by an earth fault relay
due to the system configuration. For example, an earth fault relay applied on the delta
side of a delta-star transformer is unable to detect earth faults on the star side.
However, negative sequence current will be present on both sides of the transformer
for any fault condition, irrespective of the transformer configuration. Therefore, a
negative phase sequence overcurrent element can be employed to provide time­delayed back-up protection for any uncleared asymm etrical faults downstream.

• Where rotating machines are protected by fuses, loss of a fuse produces a la rge
amount of negative sequence current. This is a dangerous condition for the machine
due to the heating effects of negative phase seque nce current and so an upstream
negative phase sequence overcurrent elem ent m ay be applied to provide back-up
protection for dedicated motor protection relays.

• It may be required to simply alarm for the presence of negative phase sequen ce
currents on the system. Operators may then investigate the cause of the unbalance.

The negative phase sequence overcurrent element has a current pick up setting ‘I2> Current
Set’, and is time delayed in operation by the adjusta bl e timer ‘I2> Time Delay’. The user may
choose to directionalise operation of the element , for either forward or reverse fault
protection for which a suitable relay characteristic angle may be set. Alternatively, the
element may be set as non-directional.

The relay menu for the negative sequence overcurre nt element is shown below:
