WebTo measure 3-phase power you need 3 wattmeters or — in OpenEnergyMonitor terms — 3 emonTxs (See note). You simply measure the three phases in the same way as you would measure three single-phase installations. You need a current transformer and a voltage monitor on each phase, and the total power is the sum of the 3 powers. WebTo calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA), and to calculate the ratio of kW/kVA. The power factor formula can be expressed in other ways: PF = (True power)/ (Apparent power) OR PF = W/VA
