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 420 - 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).
When Voltage Mode (Parameter 352) is set to any Delta base setting, L1
Apparent Power is set to 0.
Table 421 - L1 Apparent Power (Parameter 72)
L2 Apparent Power
L2 Apparent Power (Parameter 73) reports the apparent power for line 2 in kVA
or MVA depending on the configuration value for Power Scale (Parameter 377).
When Voltage Mode (Parameter 352) is set to any Delta base setting, L2
Apparent Power is set to 0.
