Total Apparent Power
Total Apparent Power (Parameter 75) reports the total apparent power of the
monitored power conductors in kVA or MVA depending on the configuration
value for Power Scale (Parameter 377). When Single or Three Phase (Parameter
176) is set to
Three Phase, Total Apparent Power is calculated as follows:
Total Apparent Power = (L1 Apparent Power + L2 Apparent Power + L3
Apparent Power)
When Single or Three Phase (Parameter 176) is set to Single Phase, Total
Apparent Power is calculated as follows:
Total Apparent Power = (L1 Apparent Power + L2 Apparent Power)
Table 280 - Total Apparent Power (Parameter 75)
L1 Power Factor
L1 Power Factor (Parameter 76) reports the power factor for line 1 in percentage.
When Voltage Mode (Parameter 352) is set to any
Delta base setting, L1 Power
Factor is set to 0.
Table 281 - L1 Power Factor (Parameter 76)
L2 Power Factor Power
L2 Power Factor (Parameter 77) reports the power factor for line 2 in percentage.
When Voltage Mode (Parameter 352) is set to any
Delta base setting, L2 Power
Factor is set to 0.
