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

Energy Monitor
The E300 Electronic Overload Relay’s energy monitor diagnostics provides
information on the electrical energy the load is consuming. The energy
diagnostics include kWh, kVARh, kVAh, kW Demand, kVAR Demand, and kVA
Demand.
