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.
General Information
1-2
Indicators
There are two indicators mounted on the front panel of the relay. The SYNC LED (present only in the
BE3-GPR P units with the sync-check option) indicates that the generator and bus inputs are within the
synchronization window set by the user. The liquid crystal display (LCD) is the main human-machine
interface and has capabilities to show any and all information necessary for programming and interpreting
relay actions.
Communications
Communication capability provides a remote serial interface between the relay and a computer. Basler
Electric offers a software package that enhances communications to BE3-GPRs. This software package
also provides a real time metering capability for monitoring generator voltage, frequency, current, watts,
power factor, and volt-amperes.
OUTPUTS
There are eleven isolated form C output contact arrangements. One for each of the nine protective
functions, the sync-check/dead bus function, and the watchdog timer.

General Information 1-3
25
Sync-Check With Dead Bus
Phase angle is settable from 2 to 20 degrees in one degree steps, and
voltage difference is adjustable from 1 to 100 Vac in one volt steps. Both
the time delay (which is variable from 0.2 to 2 seconds in 0.1 second
steps), and the slip frequency (which is variable from 0.1 hertz to 1.0
hertz in 0.1 hertz steps) qualify the in-sync condition. Dead Bus is
settable from 10 to 50 volts in increments of one volt. Accuracy is: Delta
Voltage — ±2% or ±1 V, whichever is greater throughout operating range
of 5 to 100 volts; Delta (slip) Frequency — ±0.02 Hz throughout operating
range of 0.1 to 0.5 Hz, Delta phase angle — ±0.5 degrees. This function
is an option available only on the paralleled generator version of the
relay. Repeatability is ±1.5 %.
47
Phase Balance
Phase balance measures the maximum voltage difference between any
two line-to-line phases. Trip point and reset points are settable from 5 to
100 volts in 1 volt steps. The timing is settable from 0 to 20 seconds in
one second steps. Accuracy is ±3% or ±2 V, whichever is greater
throughout operating range of 5 to 100 volts. Repeatability is ±1.0 %.
40
Loss of Excitation

neutral currents. In the five ampere CT configuration, trip point and reset
points are settable from 0.2 to 3 amperes in 0.01 ampere steps. Trip
point and reset points are settable from 0.04 to 0.6 amperes in 0.01
amperes increments, in the one ampere CT configuration. Trip timing is
adjustable from 0 to 2 seconds in 0.1 second steps. Accuracy is ±2% or
±0.01A whichever is greater throughout operating range of 0.2 to 3.0
amperes.

currents. In the five ampere CT configuration, trip point and reset points
are settable from 0.1 to 9.99 amperes in 0.01 ampere steps. Trip point
and reset points are settable from 0.10 to 2.00 amperes in 0.01 amperes
increments, in the one ampere CT configuration. Accuracy is ±2.5% or
±0.05A whichever is greater throughout operating range of 0.1 to 5.0
amperes.

Voltage Restraint: Voltage restraint compares the sensed voltage with the nominal voltage
level. A decrease of the sensed voltage (between 100% and 25% of
nominal) results in a proportional decrease of the time overcurrent pickup
point. When the sensed voltage falls below 25% of nominal, the time
overcurrent pickup point will be 25% of the actual time overcurrent setting
(see Figure 1).

BE3-GPR relays are identified by a combination of letters and numbers that make up the style number
and define the electrical characteristics and operational features. The model number, together with the
style number, describe the options included in a specific device and appear on a relay side panel.
Upon receipt of a relay, be sure to check the style number against the requisition and the packing list to
ensure that they agree.
Figure 1-2 is the style number identification chart and defines the electrical characteristics and operational
features included in BE3-GPR relays. In this example, a BE3-GPR P2BVSF is specified and has the
following features:
P - Paralleled generator protection
