Details:

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

ï BESTlogic provides the user with very high flexibility in configuring a protection and control
system.
ï Substantial functionality in a small package, useful where space is very limited but high
functionality is needed.
ï Programmable LCD display allows the relay to replace local indication and control functions, such as panel metering, alarm annunciation, and control switches.
ï Three independent communication ports with protocol support allows integration with
distributed control systems.
ï Provides optional separate ground current input for those applications where this is
required.
ï Includes frequency tracking and voltage restrained overcurrent for backup and cogeneration applications.
ï Includes Real Time Clock with 8 hour capacitor ride through and optional battery backup.
ï 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.
ï 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.
