L3 Reactive Power
L3 Reactive Power (Parameter 70) reports the reactive power for line 3 in kVAR
or MVAR depending on the configuration value for Power Scale (Parameter
377). When Voltage Mode (Parameter 352) is set to any
Delta base setting, L3
Reactive Power is set to 0. When Single or Three Phase (Parameter 176) is set to
Single Phase, L3 Reactive Power is set to 0.
Table 275 - L3 Reactive Power (Parameter 70)
Total Reactive Power
Total Reactive Power (Parameter 71) reports the total Reactive power of the
monitored power conductors in kVAR or MVAR depending on the
configuration value for Power Scale (Parameter 377). When Single or Three
Phase (Parameter 176) is set to
Three Phase, Total Reactive Power is calculated as
follows:
Total Reactive Power = (L1 Reactive Power + L2 Reactive Power + L3 Reactive
Power)
When Single or Three Phase (Parameter 176) is set to
Single Phase, Total
Reactive Power is calculated as follows:
Total Reactive Power = (L1 Reactive Power + L2 Reactive Power)
Table 276 - Total Reactive Power (Parameter 71)
L1 Apparent Power
L1 Apparent Power (Parameter 72) reports the apparent power for line 1 in kVA
or MVA depending on the configuration value for Power Scale (Parameter 377).
