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. WebElectricity consumption = Voltage x Current x Power factor x time In an electric energy meter, the voltage and current are sensed by voltage and current sensors, and the resulting signals are digitised in Analog to Digital converters.
