Frequency
Frequency (Parameter 62) reports the voltage frequency in Hertz of the
monitored power system from the E300 Electronic Overload Relay Sensing
Module.
Table 266 - 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.
