Phase Rotation
Phase Rotation (Parameter 63) reports the voltage phase rotation as ABC or
ACB of the monitored power system from the E300 relay Sensing Module.

Power Monitor
The E300 relay’s power monitor diagnostics provides information on the power
being supplied to the load. The power diagnostics include real power (kW),
reactive power (kVAR), apparent power (kVA), and power factor.
Power Scale
For large medium voltage-based power systems, it may be more convenient for
you to view the real-time power information (Parameters 64-75) in terms of
Megawatts instead of Kilowatts. Power Scale (Parameter 377) allows the E300
relay to display the values of Parameters 64…75 as Kilowatts or Megawatts.
