BUS1000/2000 Bus Bar Protection
bus1000_2000

The BUS 1000/2000 is a solid state, high speed protection system for the detection of phase-to-phase and phase-to-ground faults on bus bar installations. It can be used to protect high voltage bus bar installations of any voltage.

BUS 2000 models add to the functionality of the BUS 1000 through the metering, monitoring, event recording, waveform capture, and IRIG-B time synchronization capabilities of the DMS metering and monitoring module.

End-of-life Notice: The BUS 1000/2000 relays have been discontinued as of March 31, 2014
