10/62 Device handbook SINEAX AM2000, 173 849, 04/2015

5.4 Inputs

All voltage measurement inputs must originate at circuit breakers or fuses rated 5 Amps or
less. This does not apply to the neutral connector. You have to provide a method for
manually removing power from the device, such as a clearly labeled circuit breaker or a
fused disconnect switch.

When using voltage transformers you have to ensure that their secondary connections
never will be short-circuited.

No fuse may be connected upstream of the current measurement inputs !
When using current transformers their secondary connectors must be short-circuited

during installation and before removing the device. Never open the secondary circuit under
load.

The connection of the inputs depends on the configured system (connection type).

For the digital inputs / outputs an external power supply of 12 / 24V DC is required.

The power supply shall not exceed 30V DC !

A digital input and two digital outputs are provided as a standard.

Usage as digital input

► Clock synchronization
► Synchronization of billing intervals in accordance with energy provider
► Meter tariff switching

Technical data
Input current < 7,0 mA
Logical ZERO - 3 up to + 5 V
Logical ONE 8 up to 30 V

20/62 Device handbook SINEAX AM2000, 173 849, 04/2015

Usage as digital output

► Alarm output
► State reporting
► Pulse output to an external counter (acc. EN62053-31)

1) Recommended if input
impedance of counter > 100 kΩ

Driving a counter mechanism

The width of the energy pulses can be selected, but
have to be adapted to the counter mechanism.

Electro mechanical meters typically need a pulse
width of 50...100ms.

Electronic meters are par t l y capable to detec t puls es
in the kHz range. There are the types NPN (active
negative edge) and PNP (active positive edge). For
the AM2000 a PNP type is required. T he pulse w idth
has to be at least 30ms (acc. EN62053-31). The delay
between to pulses corresponds at least to the pulse
width. The smaller the pulse width, the higher the
sensitivity to disturbances.

Driving a relay

Rated current 50 mA (60 mA max.)
Switching frequency (S0) ≤ 20 Hz
Leakage current 0,01 mA
Voltage drop < 3 V
Load capacity 400 Ω … 1 MΩ

5.8 Analog outputs

Analog outputs are available for devices with corresponding I/O extensions only. See nameplate.

Connection to an analog input card of a PLC or a
control system

The AM2000 is an isolated measurement device. The
particular outputs are not galvanically isolat ed. To
reduce the influence of disturbances shielded a
twisted-pair cables should be used. The shield should
be connected to earth on both opposite ends. If there
a potential differences between the ends of the cable
the shield should be earthed on one side only to
prevent from equalizing currents.

Under all circumstances consider as well appropriate
remarks in the instruction manual of the system to
connect.

21/62 Device handbook SINEAX AM2000, 173 849, 04/2015

5.9 Modbus interface RS485

Via the optional Modbus interface measurement data may be provided for a superior system. However,
the Modbus interface cannot be used for device parameterization.

1) One ground connection only.
This is possibly made within the
master (PC).

Rt: Termination resistors: 120 Ω each

for long cables (> approx. 10 m)

Rs: Bus supply resistors,

390 Ω each

The signal wires (A, B) have to be t wist ed. G ND ( C/X) can be connected via a wire or via th e cabl e s c reen.
In disturbed environments shielded cables must be used. Supply resistors (Rs) have to be present in bus
master (PC) interface. Stubs should be avoided when connecting the devices. A pure daisy chain network
is ideal.

You may connect up to 32 Modbus devices to the bus. A proper operation requires that all devices
connected to the bus have equal communication settings (baud rate, transmission format) and unique
Modbus addresses.

The bus system is operated half duplex and may be extended to a maximum length of 1200 m without
repeater.

6.1 Parametrization of the device functionality

A full parameterization of all functions of the device is possible directly at the device. See: Configuration

23/62 Device handbook SINEAX AM2000, 173 849, 04/2015

6.2 Installation check

By means of the phasor diagram the correct connection of the current and voltage inputs can be checked.
In this diagram a technical visualization of the current and voltage phasors is shown, using a counter­clockwise rotation.

6.3 Simulation of I/Os

To check if subsequent circuits will work properly with the m eas urement data provided by the device,
using the service menu all analog, digital and relay outputs may be simulated, by predefining any output
value resp. discrete state.

24/62 Device handbook SINEAX AM2000, 173 849, 04/2015

7. Opera ti ng t he de vic e

7.1 Operating elements

Operation is performed by means of 6 keys:

 4 keys for navigation (

, , , ) and

for the selection of values

 OK for selection or confirmation
 ESC for menu display, terminate or

cancel

The main function of the operating keys
changes in some measurement displays,
during parameterization and in service
functions. The valid functionality of the keys is
then shown in a help bar.

7.2 Selecting the information to display

Information selection is performed via menu.

Some menu items are direct selections, other
menu items contain up to two further menu
levels.

Displaying the menu

Press ESC. Each time the key is pressed a
change to a higher menu level is performed, if
present.

Displaying information

The menu item chosen using

, can be
selected using OK. Repeat the procedure in
possible submenus until the required information
is diaplyed.

Closing the menu

After 2 min. without interaction the menu is
automatically closed and the last active
measurement display is shown.

25/62 Device handbook SINEAX AM2000, 173 849, 04/2015

7.3 Measurement displays and used symbols

For displaying measurement information the device uses both numerical and numerical-graphical
measurement displays.

Examples Measurement information

1 measured quantity

2 measured quantities

4 measured quantities

2x4 measured quantities

Graphical measurement display

Further examples

26/62 Device handbook SINEAX AM2000, 173 849, 04/2015

For defining a measurement uniquely, a short description (z.B. U1N) and a unit (z.B. V) are not sufficient.
Therefore additional symbols are used for defining the measurement type:

7.4 Alarming

The alarming concept is very flexible. Depending on the user requirements simple or more advanced
monitoring tasks may be realized.

a) The simplest approach is to define a limit value and to select a digital output to use the limit state

as its source.

b) A more advanced monitoring task may be realized using monitoring functions: Up to 3 logic inputs

may be logically combined, as well a digital output can be used to output the state of the monitoring
function. The state of each monitoring functions is also displayed in the alarm list.

c) In addition all monitoring function MFx may be combined to build a summary alarm. The state of this

summary alarm is displayed in the upper right corner of the display.

Monitoring functions

By means of monitoring functions the user can define an extended condition monitoring, e.g. for triggering
an over-current alarm, if one of the phase currents exceeds a limit value.

Logic inputs

Up to three states of limit values, logic inputs or other monitoring functions.

Logic function

For the logical combination of the inputs you can choose AND, NAND, OR, NOR, DIRECT and INVERT.
These logical functions are described in Appendix C

.

Possible follow-up actions

• Driving a logic output. The assignment of the monitoring function to a digital output / relay is done via
the settings of the corresponding output.

• State visualization in the alarm list

• Combining the states of all monitoring functions to create a summary alarm

Description

The associated descr iption will be used for visualization on the display or as a list text

Delay time ON

The condition must remain stable at least this time until it is forwarded

Delay time OFF

Waiting time until a condition, which does not longer exist, is reset

28/62 Device handbook SINEAX AM2000, 173 849, 04/2015

Summary alarm

The summary alarm combines the states of all monitoring function MFx to a superior alarm-state of the
overall unit. For each monitoring function you may select if it is used for bulding the summary alarm state.
If at least one of the enabled functions is in the alarm state, the summary alarm is also in the alarm state.

Alarm display

The symbol arranged in the status bar signalizes if alarms are active or not.
Acknowledgment: B y ack nowledg ing the summary alarm, the user confirms that he has recognized that

an alarm state occurred. The acknowledgment is done automatically as soon as the user selects the
alarm list to be displayed or if the alarm state no longer exists. By acknowledging only the flashing of the
alarm symbol stops, the symbol itself remains statically displayed until all monitoring functions are no
longer in the alarm state.

Logic output

The summary alarm can drive an output. The assignment of the summary alarm to a digital output / relay
is done via the settings of the corresponding output.

Reset: The state of the output used for the summary alarm can be reset, even if there is still an alarm
active. So, for example a horn activated via summary alarm can be deactivated. A reset may be
performed via display, a digital input or via Modbus interface. The logic output becomes active again as
soon as another monitoring function goes to the alarm state or if the same alarm becomes active again.

Alarm list

The logic output of the active summary alarm
may be reset by means of the OK key.

29/62 Device handbook SINEAX AM2000, 173 849, 04/2015

7.5 Resetting measurements

The device provides minimum and maximum values of different measured quantities, which may be reset
during operation. Reset may be performed in groups using the service menu.

Group Values to be reset

1 Min/max values of voltages, currents and frequency
2 Min/max values of Power quantities (P,Q,Q(H0),D,S); min. load factors
3 Min/max values of power mean-values, bimetal slave pointers and free selectable mean-values
4 Maximum values of harmonic analysis: THD U/I, TDD I, individual harmonics U/I
5 All imbalance maximum values of voltage and current

7.6 Setting / resetting of meter contents

Meter contents may be individually set or reset during operation using the service menu.

7.7 Configuration

A full parameterization of the device can be performed via the menu settings. With the exception of the

“country and clock” menu, all modifications will not take effect before the user accepts the query “Store
configuration changes” when leaving the settings menu.

• Country and clock: time/date, date format, display language

• Display settings: Refresh rate, brightness, screen saver

• Measurement input: System type, nominal values of U/I/f, sense of rotation, quadrants

• Power mean-values: Interval time, synchronization source

• Free selectable mean-values: Measured quantity, interval time, synchronization source

30/62 Device handbook SINEAX AM2000, 173 849, 04/2015

7.8 Timeouts

The device is designed to display measurements. So, any other procedure will be terminated after a

certain time without user interaction and the last active measurement image will be sho wn again.

Menu timeout

A menu timeout takes effect after 2 min. without changing the present menu selection. It doesn’t matter if

the currently displayed menu is the main menu or a third sub-menu: The menu is closed and the last
active measurement image is displayed again.

Configuration timeout

After 5 min. without interaction in a parameter selection or during entering a value in the settings menu,
the active configuration step is closed and the associated parameter remains unchanged. The follow-up
procedure depends on what you have done before:

• If the user did not change configuration parameters before the aborted step, the main menu will be
displayed and the device starts to monitor a possible menu timeout.

• If the user changed configuration parameters before the aborted step, the query “Store configuration
changes?” is shown. If the user does not answer this query within 2 min. this dialogue is closed: The
changed configuration will be stored and activated and then the last active measurement image is
displayed again.

Reactive power

Most of the loads consume a combination of ohmic and inductive current from the power system. Reactive
power arises by means of the inductive load. But the number of non-linear loads, such as RPM regulated
drives, rectifiers, thyristor controlled systems or fluorescent lamps, is increasing. They cause non­sinusoidal AC currents, which may be represented as a sum of harmonics. Thus the reactive power to
transmit increases and leads to higher transmission losses und higher energy costs. This part of the
reactive power is called distortion reactive power.

Normally reactive power is unwanted, because there is no usable active component in it. Because the
transmission of reactive power over long distances is uneconomic, it makes sense to install compensation
systems close to the consumers. So transmission capacities may be used better and losses and voltage
drops by means of harmonic currents can be avoided.

P: Active power
S: Apparent power including harmonic

components

S1: Fundamental apparent power

Q: Total reactive power
Q(H1): Fundamental reactive power

D: Distortion reactive power

The reactive power may be divided in a fundamental and a distortion component. Only the fundamental
reactive power may be compensated directly by means of the classical capacitive method. The distortion
components have to be combated using inductors or active harmonic conditioners.

The load factor PF is the relation between active power P and apparent power S, including all possibly
existing harmonic parts. This factor is often called cosφ, which is only partly correct. The PF corresponds
to the cosφ only, if there is no harmonic content present in the system. So the cosφ represents the
relation between the active power P and the fundamental apparent power S(H1).

The tanφ is often used as a target quantity for the capacitive reactive power compensation. It
corresponds to the relation of the fundamental reactive power Q(H1) and the active power P.

Power factors

The power facto r PF gives the relation

between active and apparent power. If
there are no harmonics present in the
system, it corresponds to the cosφ. The
PF has a range of -1...0...+1, where the
sign gives the direction of energy flow.

The load factor LF is a quantity derived
from the PF, which allows making a
statement about the load type. Only this
way it's possible to measure a range like

0.5 capacitive ... 1 ... 0.5 inductive in a
non-ambiguous way.

The reactive power factor QF gives the
relation between reactive and apparent
power.

Zero displacement voltage UNE

Starting from the generating system with star point E
(which is normally earthed), the star point (N) on load
side is shifted in case of unbalanced load. The zero
displacement voltage between E und N may be
determined by a vectorial addition of the voltage vectors
of the three phases:

UNE = - (U1N + U2N + U3N ) / 3

A displacement voltage may also occur due to
harmonics of order 3, 9, 15, 21 etc., because the
dedicated currents add in the neutral wire.

Earth fault monitoring in IT systems

Via the determination of the zero displacement voltage it's possible to detect a first earth fault in an
unearthed IT system. To do so, the device is configured for measurement in a 4-wire system with
unbalanced load and the neutral connector is connected to earth. In case of a single phase earth fault
there is a resulting zero displacement voltage of ULL/ √3. The alarming may be done e.g. by means of a
relay output.

Transformer, secondary side Load

Because in case of a fault the voltage triangle formed by the three phases does not change, the voltage
and current measurements as well as the system power values will still be measured and displayed
correctly. Also the meters carry on to work as expected.

The method is suited to detect a fault condition during normal operation. A declination of the isolation
resistance may not be detected this way. This should be measured during a periodical control of the
system using a mobile system.

Another possibility to analyze fau lt condit ions in a grid offers the method of the symmetrical components
as described in A3.

Harmonics

Harmonics are multiples of the fundamental resp. system frequency. They arise if non-linear loads, such
as RPM regulated drives, rectifiers, thyristor controlled systems or fluorescent lamps are present in the
power system. Thus undesired side effects occur, such as additional thermical stress to operational
resources or electrical mains, which lead to an advanced aging or even damage. Also the reliability of
sensitive loads can be affected and unexplainable disturbances may occur. In industrial networks the
image of the harmonics gives good information about the kind of loads connected. See also:

► Increase of reactive power due to harmonic currents

TDD (Total Demand Distortion)

The complete harmonic content of the currents is calculated additionally as Total Demand Distortion,
briefly TDD. This value is scaled to the rated current resp. rated power. Only this way it's possible to
estimate the influence of the current harmonics on the connected equipment correctly.

Maximum values

The maximum values of the harmonic analysis arise from the monitoring of THD and TDD. The maximum
values of individual harmonics are not monitored separately, but are stored if a maximum value of THD or
TDD is detected. The image of the maximum harmonics therefore always corresponds to the dedicated
THD resp. TDD.

The accuracy of the harmonic analysis strongly depends on the quality of the current and voltage
transformers possibly used. In the harmonics range transformers normally change both, the
amplitude and the phase of the signals to measure. It's valid: The higher the frequency of the
harmonic, the higher its damping resp. phase shift.

Imbalance in three-phase systems may occur due to single-phase loads, but also due to failures, such as
e.g. the blowing of a fuse, an earth fault, a phase failure or an isolation defect. Also harmonics of the 3rd,
9th, 15th, 21st etc. order, which add in the neutral wire, may lead to imbalance. Operating resources
dimensioned to rated values, such as three-phase generators, transformers or motors on load side, may
be excessively stressed by imbalance. So a shorter life cycle, a damage or failure due to thermical stress
can result. Therefore monitoring imbalance helps to reduce the costs for maintenance and extends the
undisturbed operating time of the used resources.

Imbalance or unbalanced load relays use different measurement principles. One of them is the approach
of the symmetrical components, the other one calculates the maximum deviation from the mean-value of
the three phase values. The results of these methods are not equal and don't have the same intention.
Both of these principles are implemented in the device.

Symmetrical components (acc. Fortescue)

The imbalance calculation method by means of the symmetrical components is ambitious and intensive to
calculate. The results may be used for disturbance analysis and for protection purposes in three-phase
systems. The real existing system is divided in symmetrical system parts: A positive sequence, a negative
sequence and (for systems with neutral conductor) a zero sequence system. The approach is easiest to
understand for rotating machines. The positive sequence represents a positive rotating field, the negative
sequence a negative (braking) rotating field with opposite sense of direction. Therefore the negative
sequence prevents that the machine can generate the full turning moment. For e.g. generators the
maximum permissible current imbalance is typically limited to a value of 8...12%.

Maximum deviation from the mean value
The calculation of the maximum deviation from the mean value of the phase currents resp. phase
voltages gives the information if a grid or substation is imbalanced loaded. The results are independent of
rated values and the present load situation. So a more symmetrical system can be aspired, e.g. by
changing loads from one phase to another.

Also failure detection is possible. The capacitors used in compensation systems are wear parts, which fail
quite often and then have to be replaced. When using three phase power capaci t or s all phases will be
compensated equally which leads to almost identical currents flowing through the capacitors, if the system
load is comparable. By monitoring the current imbalance it's then possible to estimate if a capacitor failure
is present.

The maximum deviations are calculated in the same steps as the instantaneous values and therefore are
arranged there (see A1

).

The device calculates automatically the mean values of all system power quantities. In addition up to 12

further mean value quantities can be freely selected.

Calculating the mean-values

The mean value calculation is performed via integration of the measured instanta neous va lues ov er a
configurable averaging inte r val. The interval time may be selected in the range from one second up to one
hour. Possible interim values are set the way that a multiple of it is equal to a minute or an hour. Mean
values of power quantities (interval time t1) and free quantities (interval time t2) may have different
averaging intervals.

Synchronization

For the synchronization of the averaging intervals the internal clock or an external signal via digital input
may be used. In case of an external synchronization the interval should be within the given range of one
second up to one hour. The synchronization is important for making e.g. the mean value of power
quantities on generating and demand side comparable.

Trend

The estimated final value (trend) of mean values is determined by weighted addition of measurements of

the past and the present interval. It serves for early detection of a possible exceeding of a given maximum
value. This can then be avoided, e.g. by switching off an active load.

History

For mean values of system powers the last 5 interval values may be displayed on the device or read via

interface. For configurable quantities the value of the last interval is provided via communication interface.

Bimetal current

This measured quantity serves for measuring the long-term effect of the current, e.g. for monitoring the
warming of a current-carrying line. To do so, an exponential function is used, similar to the charging curve
of a capacitor. The response time of the bimetal function can be freely selected, but normally it
corresponds to the interval for determining the power mean-values.
