Frequency
Frequency (Parameter 62) reports the voltage frequency in Hertz of the
monitored power system from the E300 Electronic Overload Relay Sensing
Module.
Table 410 - Frequency (Parameter 62)
Phase Rotation
Phase Rotation (Parameter 63) reports the voltage phase rotation as ABC or
ACB of the monitored power system from the E300 Electronic Overload Relay
Sensing Module.

Power Monitor
The E300 Electronic Overload 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
Electronic Overload Relay to display the values of Parameters 64…75as Kilowatts
or Megawatts.
