where

P_{1} = reading of watt-meter 1

P_{2} = reading of watt-meter 2

P_{3} = reading of watt-meter 3

V_{1} = voltage difference between 1 and c

V_{2} = voltage difference between 2 and c

V_{3} = voltage difference between 3 and c

I_{1} = current through watt-meter 1

I_{2} = current through watt-meter 2
