Calculate total power consumed by the 3 load and the power factor.

2 wattmeter are used to measure power in a 3ø balanced delta connected load using 2 wattmeter are method. The readings of the 2 wattmeter are 500W and 2500W respectively. Calculate the total power consumed by the 3ø load and the power factor. - Mumbai University > FE > Sem 1 > Basic Electrical and Electronics Engineering

In delta connection

W1=500w

W2=2500w

Total power absorbed = P=W1+W2=3000w

Assume logging p.f.

=tan1[3(w1w2w1+w2)]=tan1{3(2000)3000}=49.10660power factor=cos=0.6546(logging)
