Delta measurement with an MPQ2000

Delta measurement with an MPQ2000

The power measurement for a delta configuration uses a 2 wattmeter method even thoughtheyare 3 phases. 

When measuring a wye,all the voltages are referenced to neutral,referred to as line voltages. The measured currents are also line currents. Since both the voltage and currents are line values,the measurement does not introduce any phase shift.
