on-board real time clock.

¼ cycle of 60 Hz.

Standard model relays have the following special
features:

• Three shot recloser.

• Pre-insertion breaker resistor operations counter
with programmable reset and block reclose signal.

• Six configurable timing diagnosic logs, each with an
optional alarm setting. This feature can be used to
monitor various protection system parameters, such

• Twelve entry fault log detailing the system and relay
status at the time the fault trigger occurrred.

• Twelve entry COMTRADE fault record consisting of
configuration and data files. Data contains 4 cycles
of pre-fault and 16 cycles of post-fault data.

• Integrated I2t breaker contact duty monitor with
alarm.

APPLICATIONS

The BE1-BPR provides both breaker protection and breaker monitoring in a single unit that can communicate with
a local or remote computer.

BREAKER PROTECTION

Breaker protection includes breaker fail protection,
breaker resistor protection, and protection against
sustained arcs across one or more open breaker
contacts.

Breaker-fail protection is accomplished by initiating a
BPR timer from one or more relay trip signal inputs and
providing an output to trip upstream breakers if the
BPR fault detectors don’t drop out before the time
expires on the BPR timer.

Breaker opening resistor protection is accomplished by
providing an output to block reclosing if BPR calcula­tions determine that additional breaker operations
could exceed the maximum resistor power rating.

Open breakers can be protected against sustained
arcs by providing an output to close the breaker and
allow it to trip again. Such sustained arcs can be
initiated by lightning or loss of dielectric strength. Arc
current may be limited to line charging current and
may go undetected by standard fault protection
elements. If the arc is allowed to continue for minutes,
the breaker will be destroyed due to the internal heat
generated. The BPR provides a separate fault detector
for detecting low level arcs.

BREAKER MONITORING

Breaker monitoring generally consists of gathering
the data necessary to predict when the breaker con­tacts should be serviced. This practice eliminates the
need to perform routine maintenance on breakers that
may be in good condition. Data is acquired each time a
52a/b contact input indicates opening of the breaker.

The BPR not only monitors contact wear but also
gathers data on breaker-fail timing margins. This
information may be used to help the user achieve fast,
secure breaker-fail protection. Data is acquired each
time the breaker operates.

The BPR also captures fault data on all four current
inputs, along with status on all contact inputs and relay
outputs.

The BPR stores the last 12 fault records and overwrites
the oldest when full. Recording is triggered according
to the trigger conditions that were set up while pro­gramming the relay logic.

Fault data is stored in three forms: An oscillographic
record in COMTRADE format, a fault data summary
report, and a fault record list.

All data captured can be retrieved by a PC equipped
with standard off-the-shelf communications software.

PROGRAMMING LANGUAGE

The powerful nature of the BESTlogic programming language can be shown by the simple program used to
achieve the logic shown in Figure 2. The program is as follows:

LN=BFL2E LI6=4,12 LOA=T4+O14+O15* LO9=T3I6
LF1=PI,1 LI7=4,12 LO1=O2 LO10=I6+O11
LF2=NI,1 LR=0,0,0,0,0 LO2=T1O7+F1T2+O1O7 LO11=I3+I4+IT5
LF3=PI,2 LT=D,O8,/O8 LO3=O13 LO12=F3I1
LI1=4,12 LT2=D,O9,/O9 LO4=T5
LI2=4,12 LT3=C,O10,/O10 LO5=T3
LI3=4,12 LT4=D,O6,/O6 LO6=/I1/I2
LI4=4,12 LT5=D,O12,/O12 LO7=F1+F2
LI5=4,12 LT6=0,0,0 LO8=T3O11

*The non-maskable alarms are always ORed with the programmable diagnostics to aprovide an alarm output.

The BESTlogic commands provide an easy way to define functional elements and use them in logical expressions
to achieve the operation desired. Once programmed, different logic sets are activated simply by changing the
name of the active logic set using the LOGIC command. Please see the instruction manual for details.

FUNCTIONAL DESCRIPTION

Figure 2 - Example of programmable logic (BFL2E)

BFL2E logic in figure 2 provides the following application features:

1. Three-Pole Tripping BF Logic (Output latch-in provided and Control timer limits operational window). Three
BFI inputs are available at IN3, IN4, and IN5 to start delay timer T1. If the BFI inputs are not reset by the time
T1 times out and either the phase (F1) or neutral (F2) fault detector is still picked up, then outputs BFO1 and
BFO2 will close to trip the backup breakers. Control timer (T3) is used to limit the breaker failure window of
opportunity.

2. Single-Pole Tripping BF Logic (Features: Output latch-in provided and Control timer limits operational
window). If single-pole tripping is used, a BFI input is available (IN6) to start delay timer T2. This input is only
supervised by the phase fault detector (F1). If the BFI input (IN6) is not reset by the time the timer T2 times
out and the phase fault detector (F1) is picked up, outputs BFO1 and BFO2 close, tripping the backup
breakers. Control timer T3 is used to limit the breaker failure window of opportunity. Neutral fault detector (F2)
is not used to supervise the single-pole BF logic, because F2 is still picked up by the phase imbalance after the
fault clears. Three-phase BF logic is inhibited during this period, because there is no 3-phase BFI input active.

3. Trip Coil Status Monitor. Preprogrammed logic is provided using IN1 to provide breaker status and IN2 for
trip coil continuity.

4. Breaker Arc Protection. Preprogrammed logic is provided using fault detector (F3) for the moving average
fault detector, IN1 for breaker status and OUT4 for the arc detector output.

5. Block Reclose Output. Preprogrammed logic is provided using breaker resistor protection output (O13) to
drive the Block Reclose (BR) output (OUT3).

6. Retrip Output. A Retrip output is provided to give a backup trip signal to the breaker trip coil. This can either
provide a separate path to a single trip coil or be hooked to the backup trip coil if available.

7. External Fault Trigger. The enhanced BE1-BPR relay provides the ability to save COMTRADE fault records for
twelve events in memory at one time. An external fault trigger is provided to allow other multiple units to record
the same event.

8. Alarm Output. An Alarm output is provided to signal relay failure or diagnostic alarm.
