The BE1-GPS100 is a multifunction, programmable numerical protection, meter, and control

relay. Functions provided include three phase voltage controlled, voltage restrained, or

standard overcurrent, phase residual and independent ground overcurrent, negative sequence

overcurrent, breaker failure, over/underfrequency, phase over/undervoltage, zero sequence

over/undervoltage, and negative sequence overvoltage, forward or reverse power, loss of

excitation, volts per hertz, sync check, sensitive third harmonic ground fault monitoring, breaker

monitoring and control and metering functions, all in an integrated system.

ADVANTAGES

BESTlogic provides the user with very high flexibility in configuring a protection and control

system.

Substantial functionality in a small package, useful where space is very limited but high

functionality is needed.

Programmable LCD display allows the relay to replace local indication and control func

tions, such as panel metering, alarm annunciation, and control switches.

Three independent communication ports with protocol support allows integration with

distributed control systems.

Provides optional separate ground current input for those applications where this is

required.

Includes frequency tracking and voltage restrained overcurrent for backup and cogenera

tion applications.

Includes Real Time Clock with 8 hour capacitor ride through and optional battery backup.

Available in fully drawout half rack case. Two Basler Electric half rack IEDs (Intelligent

Electronic Devices) can be dovetailed together to mount in a standard 19-inch equipment

rack with no special mounting hardware.

Available in fully drawout S1 case with test paddle. The S1 case, with available adapter

plates, fits cutout, drilling and behind panel projection dimensions for common Basler

Electric, GE and Westinghouse unit case relays.
