Power Scale
For large medium voltage based power systems, it may be more convenient for the
user 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 64-75 as Kilowatts
or Megawatts.
Table 268 - Power Scale (Parameter 377)
L1 Real Power
L1 Real Power (Parameter 64) reports the real power for line 1 in kW or MW
depending on the configuration value for Power Scale (Parameter 377). When
Voltage Mode (Parameter 352) is set to any
Delta base setting, L1 Real Power is
set to 0.
Table 269 - L1 Real Power (Parameter 64)
L2 Real Power
L2 Real Power (Parameter 65) reports the real power for line 2 in kW or MW
depending on the configuration value for Power Scale (Parameter 377). When
Voltage Mode (Parameter 352) is set to any
Delta base setting, L2 Real Power is
set to 0.
