Communicates with central office

Download Bulletin UHG for more information or download the instruction manual.

BESTview for the BE1-BPR, Version 1.02.01 can be downloaded.

BESTView application software provides a simple terminal interface to communicate with the BE1-BPR Breaker Protection Relay, retrieve and display COMTRADE oscillographic fault data, and provide a remote front panel interface.

This software is not required to communicate with the relay.However, it combines the functions of a number of separate packages into one program that is optimized for the BE1-BPR relay.

BE1-25A Automatic Synchronizer

Provides precise synchronization of generator(s) to a power system.
Multiple breaker with six programmable closing times for up to six generators

Plug-in modules for:
- Voltage acceptance
- Voltage matching
- Frequency matching
- Dead bus closing

Voltage Adjustment function has three options for coordination with regulating system
Real time adaptive speed control with smart target pulse
For use with standard motor operated controls or digital adjuster
Nineteen inch rack mount unit including built-in test provisions

Download Bulletin UIM for more information or download the instruction manual.

For details on utilizing the BE1-25A as a replacement for an XM Synchronizer, see the Comparison BE1-25A and Eaton XM Synchronizer spreadsheet.

A BE3-25A Single Phase Auto-Synchronizer also is available.

BE1-25 Sync-Check Relay

Checks for proper phase angle and voltage (option) before closing breaker.

Direct reading thumbwheel switches for setting angle and delay
May be set to respond as fast as 1 cycle
of 50/60 Hz
Better than 1 degree accuracy

Voltage monitoring provides independent check of bus and line conditions (optional )
SCADA control of phase window for emergency closure of critical ties

BE3-GPR Generator Protective Relay

The BE3-GPR is a microprocessor-based relay designed for enhanced performance, accuracy, communication and sophistication in a single package. Although designed for the rugged and environmentally challenging requirements of an industrial setting, the BE3-GPR is constructed in accordance with the IEEE C37.90 standards, as demanded by utilities.

Available in neutral ground fault or voltage restrained three phase time overcurrent.
Wide range trip and reset adjustments
Programmable time delays
Selectable single phase, three-phase three-wire, three-phase four-wire voltage input
True RMS sensing
1A or 5A CT inputs
“Form C” output contact for every tripping function, with front panel or PC set-up
UL and CSA certified
Meets ANSI/IEEE C37.90.1-1989 for Surge Withstand and Fast Transient
BESTCOMS GUI software available to aid in setup.

Available in semiflush or behind-the-panel mounting configuration

Windows-based PC software is available for set-up and generator metering. The BE3-GPR is available with an auxiliary 125/250 V power supply as option.
