Three unequal, single phase inductive loads are connected between the lines 1-2, 2-3 and 3-1 of a 3 phase system. The line potentials are each 230V with V12 leading V23. The first load takes 100A at 0.707 pf, the second takes 150A at 0.8 pf and the third takes 28.4KW at 0.5 power factor. What will be the value of the two wattmeter connected for the two wattmeters method in measuring power if the current coils were in lines a and 2?
