Metering and Diagnostics Chapter 8
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 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.
