A balanced 3-Q , connected load drwas power from 440 V supply . The two wattmeter connected indicate w1 = 4.2 kw and w2 = 0.8 kw

calculate:

a ) the power

b ) power factors

c ) current in circuit --------

I try to solve ::

A ) power = 4.2 + 0.8 = 5

B ) (w1 - W2 / w1 + w2 ) =0.68

power pactor = cos tan-1 0.68 = 0.82

C ) Il = p/v = 0.82/ 440 = 1.8X10^3
