Power Relay
Description
The G2000 Power Relay is intended for detection of power
level for protection, control and monitoring purposes. In
the default configuration, the G2000 acts as a reverse
power relay for protection of generators running in parallel.
Basic adjustments can be done on the dials on the front
panel. More configuration options are available through PC
configuration via the optional G0100 Programming Kit. PC
programming enables the user to reconfigure the relay as an
overload relay and allows extension of the ranges on the dials
on the front panel.
One version covers all system voltages from 63 Vac to
690 Vac. Rated voltage can be adjusted by a preset button or
PC configuration. Auxiliary supply voltage is 24 Vdc.
