Using an external modem, you can also access the relay’s user interface
through a telephone link between the relay and your computer.
Connect the serial port on the external mode
m to Port 2 on the relay’s back
panel. Both devices are configured as RS-232 DCE devices with female connectors, so the cable between the relay a
nd the modem requires a crossover and
a gender change. Alternatively, you can use the ERLPhase modem port adapter
provided with the relay to make Port 2 appear the same as a PC’s serial port. A
standard modem-to-PC serial cable can then be used to connect the modem and
the relay. For pin-out details see “Communication Port Details” on page 2-8.
Connect the modem to an analog telephone line or switc
h using a standard RJ-
11 connector.
You must appropriately configure the relay’s Port 2
to work with a modem.
Log into the relay through a direct serial link, go to the Utilities>Setup>Ports
screen, and set Port 2 Modem option to Yes. Set the Baud Rate as high as possible — most modems handle 57,600 bps. The Init
ialize setting allows you to
set the control codes sent to the modem at the start of each connection session.
The factory defaults are: “M0S0=0&B1” for an external modem and
“M0S0=0” for an internal modem.

Figure 2.4: Network Link
You can access both the relay’s user interface and DNP3 SCADA services simultaneously through the same network port with an
optional Ethernet TCP/IP
LAN link. If the Ethernet option has been installed, Port 5 on the rear panel will
be labelled “NETWORK.”
The user interface accessed through the LAN is the same as that available
through
a direct serial connection or a modem link, but requires the use of a
Telnet client on your PC. The HyperTerminal program included with Microsoft Windows provides Telnet services. To
select Telnet, go to HyperTerminal’s Properties dialog box and set the Connect Using field to TCP/IP (Winsock). If t
his option is not available in the pick list, you require a newer
version of HyperTerminal (v1.2 or greater). Alternatively, you can use any
Telnet program that fully supports VT-100 terminal emulation and z-modem
file transfer.
DNP3 SCADA services can also be accessed over the LAN, for details see
“Accessing the SCADA Services” on page 2-7.
Connect Port 5 to the Ethernet LAN using
an appropriate 10BaseT cable with
an RJ-45 connector. The relay supports 10 Mbit Ethernet, although a dual
speed 10/100 Ethernet hub or switch can be used.
By default, the relay is assigned an IP address of 192.168.1.100. If this address
is not suitable, it
may be modified using the relay’s Maintenance Menu. For
details see “Using HyperTerminal to Access the Relay’s User Interface” on

Using HyperTerminal to Access the Relay’s User Interface
Change settings, view measured values and retrieve data from the relay using
its user interface. This section describes how to configure a standard Windows
VT-100 terminal program on your PC for use with the relay.
The computer must be connected to the relay by one of its serial, modem or
rnet communication ports, for details see “Communicating with the Relay
Ethe
(IED)” on page 2-2.
The relay user interface is accessed using a sta
program on your computer eliminating the need for specialized user interface
software. Any terminal program that fully supports VT-100 emulation and provides z-modem file transfer services can be used. The
included with Microsoft Windows is used here as an example.
Configure your terminal program as described in
the appropriate serial port, modem or TCP/IP socket on your computer.

the relay and the user. From here the user can set the relay, load a setting file,
view metering information, create and retrieve recordings, view logs, set-up
system parameters and review system information. The following steps describe how to access the TUI.

Differential Zone Selection and CT Input Assignment
The B-PRO can be configured for a number of different differential zones.
These zones are defined as:
• Bus1
• Bus1 and Transformer
• Transformer Only
• Bus1 and Bus2
Bus1 zone allows up to 6 current inputs
(87B-1). All CT’s used for Bus Protection must be wired in wye.
Bus1 and Transformer zone allows up to 5 current in
zone and 2 inputs for the transformer zone. In this configuration, Input 5 is used
for both the bus zone and the transformer zone. Inputs 1-4 are used for the bus
zone. Input 6 is used for the transformer zone only. Inputs 1-5 must be wired
in wye, but input 6 can be wired in wye or delta.
Transformer Only zone uses inputs 5 and 6 in the transformer
(87T). Input 5 must be wired in wye, but input 6 can be wired in wye or delta.
Bus1 and Bus2 are used where 2 zones o

Digital Control
Each CT input can be automatically excluded from all relaying, metering and
recording functions based on the status of an associated external input. To set
this feature, the Digital Control of the CT input must be enabled, the associated
external input selected, and the state of "Exclude When" set. The CT input will
be automatically excluded from all relaying, metering and recording functions
when the status of the associated external input agrees with the "Exclude
When" setting. This feature can be used to automatically adjust the CT inputs
of a differential zone based on the changes in the bus configuration. The connections of "Exclude When" setting accommodates the use of "a" or "b" auxiliary contact as the digital control
input.

The CT saturation detection and Trip-Bloc
king scheme are composed of two
parts: the first part is to deal with the fast CT saturation, i.e. CT saturates in the
first cycle after the fault occurs; the second part is to deal with the slow CT saturation, i.e. CT saturates after the first cycle.

Detection of Fast CT Saturation
Rather than examination of individual line fault currents for the presence of
saturation, the detection method uses only IO and IR for its block/no-block decision. A novel algorithm (patent pending) has been
fast CT saturation quickly, sensitively and accurately. The core of this algorithm is to check the phase relationship of
fault, both IO and IR start to increase simultaneously and they are always kind
of in phase. For an external fault, the phase dIO/dt is always lagging dIR/dt.
Detection of Slow CT Saturation
Sometimes CT does not saturate in the first cycle after the fault occurs due to
the DC offset and the CT core remnant. Under these conditions, the algorithm
described in above "Detection of Fast CT Saturation" could miss the detection
of the changes of IR and IO, because of the limit of the sample window size in
the DFT calculation. A "block zone" under the differential characteristic curve
as shown in Figure 4.3 is defined to solve this.

Additional SecurityFor additional security, some pickup delays are also applied to the differential
protection function as described below.
IOmin and Slope1 (S1)
As shown in Figure 4.6, when the IO, IR trajectory enters into the trip zone
from IOmin or slope1 region, a 6 ms (8 ms for 50Hz system) pickup delay is
applied so as to be certain that the IO, IR trajectory has reliably come into the
trip zone. To ensure the fast operating speed of 87B function for internal faults,
IRs should be set to be greater than the maximum bus transfer load plus safety
margin. The safety margin should be greater than S1/100 per unit. In this way,
the IO, IR trajectories for internal faults are always entered into the trip zone
from the IOmin and slope1 region rather than from the slope2 region under any
pre-fault conditions.
Figure 4.6: Pickup Delay for Additional Security
Slope2 (S2)
When a slow CT saturation occurs during an external fault as described in page
4-3, the IO, IR trajectory may enter the trip zone, but always from the slope2
region. In most cases when the slow CT saturation occurs, the IO, IR trajectory

will enter into the saturation block zone first so that the block flag will be set
and 87B trip will be blocked accordingly. However, in some special situations
when the fault current contains low AC current combined with high magnitude
slow decaying DC current, the external fault current level may not be high
enough to bring the IO, IR trajectory into the saturation block zone, but it might
still bring the IO, IR trajectory into the trip zone from slope2 region for a short
period of time (the CT recovers to normal quickly). In order to make the relay
secure under these special situations, a 36 ms (45ms for 50Hz system) pickup
delay is applied. As described before, this delay does not affect the operating
speed for internal faults.
IOH High Setting
There is no any intentional delay as long as the IO exceeds the IOH setting
threshold no matter where the IO, IR trajectory comes from. The purpose of the

Protection
87T Transformer Differential
Device 87T is the differential protection for the transformer zone. It can be
used when the differential zone is selected as Bus1 & Transformer or Transformer Only. The device operates for internal faults and provides restraint
for
external faults, transformer energization or transformer over excitation conditions. CT input 5 and CT input 6 are dedicated for the differential device when
2 differential
zones (bus and transformer) are selected, or if only 1 differential
zone (transformer) is selected. If external control is enabled, and asserted, the
ac analog current will be excluded from all relay, metering and recording functions.
Restraint quantities are summed;
the magnitude sum is then divided by two.
Operating quantities are summed vectors.
Device 87T has 2nd and 5th harmonic blocking, each element is set independent of each other. If an input phase current is less
than 5% of I nominal, this
current will not be used for the 2nd and 5th harmonic blocking calculation. For
a 5A relay this equals 0.25A.
As shown below, the 2nd harmonics restraint si
gnal is stretched for 5ms in the
first cycle on transformer energization to prevent the 2nd harmonics restraint
signal from any possible momentary reset due to the current signal transition
in the first cycle. Note that this logic only becomes active when the transformer
has been de-energized or very lightly loaded (the restraint current is less than

50BF Breaker Failure
Breaker failure protection function is used to detect breaker failures and react
correspondingly. This function is provided on all the current inputs. When
breaker failure is initiated by a trip (user-settable: include 87B-1, 87B-2, 87T,
ProLogic, External Input or its own O/C functions) and the breaker current still
exists, two timers (T1 and T2, user settable) will be started. After these timers
are timed out, if the current still exists (which indicates breaker failure), the
output of this function will be set high.
The two outputs of this function can be used to
trip another trip coil or the next
level of breakers, such as bus breakers. For example set T1 to 10 ms and T2 to
200 ms, and then use the output of T1 to send a trip to the associated circuit
breaker before sending the output of T2 to the bus or transformer protection. If
the output of T1 tripped the circuit breaker before T2 timed out the current input would dropout and you would not clear the whole transformer or bus zone.

This function operates on fundamental quantities of the highest phase current
of the 3 phases. Two sets of phase time overcurrent protection functions on

You can set Nominal CT Secondary Current to either 5 A or 1 A and
Nominal System Frequency to either 60 Hz or 50 Hz. This example
is set to 5 A/60 Hz.
Relay testing is required to determine if B-PRO performs correctly after the
settings are complete or to determine verification of relay settings needed. In
most cases a simple test using three voltage sources and three current sources
is adequate. Testing the bus differential element requires up to six sets of three
phase current sources when used in full capability. Use all the available metering functions during testing to verify
current signals.

Some Additional
Points to Consider
In all of the test cases, B-PRO can be set to trigger a transient fault record. Once
this is done, the fault record can be viewed, as can the point where the operation point crosses into the trip region. Als
rents can be performed to test all the functions of the relay. That is,
differential function between HV and LV can be performed. A test using all 15
currents could be performed. This presumes that fifteen synchronized currents
are available. A verification of operate IO and restraint IR quantities is possible
through the TERMINAL MODE by selecting the OPERATING QUANTITIES sub-menu. This screen indicates
