GENERAL INFORMATION

DESCRIPTION

BE3-GPRs (Generator Protective Relays) use microprocessor based technology to provide total generator
protection in a single package. This microprocessor design allows for exact setpoint adjustment and
precise generator system protection. BE3-GPRs allow for quick and simple setup via a personal computer
or front panel human machine interface. Because the BE3-GPRs have low sensing burdens, no
dedicated PTs and CTs are required. Optional protective features allow for customizing the BE3-GPRs to
meet your system requirements. The BE3-GPR provides multiple functions in a single case -- a
combination that yields significant savings in installation and setup.

CAPABILITIES

BE3-GPRs are packaged in metal cases for improved electromagnetic compatibility. They are moisture
and dust resistant. Each device provides protection for stand-alone, isolated generating systems or
paralleled generating systems. Models with the following protective functions are available.

Basic Stand-Alone Generator Version

•

27/59 Under/Over voltage protection

•

81O/U Under/Over frequency protection

•

81U

Underfrequency

Basic Paralleled Generator Version:

•

27/59

Under/Over voltage protection

•

81O/U Under/Over frequency protection

•

81U Underfrequency

•

32R

Reverse power protection

Optional Protective Functions

•

51V

Time Overcurrent

•

51N

Neutral fault current protection

•

40

Reactive current (loss of excitation) protection (Paralleled Version Only)

•

47

Phase balance protection

•

25

Sync-check/dead bus closing (Paralleled Version Only)

Model combinations depend on the selected style.

Control Enables

Four hardware jumpers enable the following special protective features. Each feature is continuously
monitored by software within the microprocessor. They are:

•

Trip reset

•

Program enable

•

Failsafe enable

•

Output enable

Watchdog Timer

The watchdog timer monitors the microprocessor for proper software and microprocessor operation. If
there is an occurrence that inhibits proper operation, the watchdog timer de-energizes the watchdog timer
output contacts to annunciate the problem to the system.
