Table 282 - L2 Power Factor (Parameter 77)
L3 Power Factor
L3 Power Factor (Parameter 78) reports the power factor for line 3 in percentage.
When Voltage Mode (Parameter 352) is set to any
Delta base setting, L3 Power
Factor is set to 0. When Single or Three Phase (Parameter 176) is set to Single
Phase, L3 power factor is set to 0.
Table 283 - L3 Power Factor (Parameter 78)
Total Power Factor
Total Power Factor (Parameter 79) reports the total power factor of the
monitored power conductors in percentage. When Single or Three Phase
(Parameter 176) is set to
Three Phase, Total Power Factor is calculated as follows:
Total Power Factor = (L1 Power Factor + L2 Power Factor + L3 Power Factor) / 3
When Single or Three Phase (Parameter 176) is set to Single Phase, Total Power
Factor is calculated as follows:
Total Power Factor = (L1 Power Factor + L2 Power Factor) / 2
