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.
