If δ is the loss angle of the cable, then its power factor is
-
- sin δ
- cos δ
- independent of δ
- depends upon δ but it is not as per (a) and (b)
Correct Option: A
Figure depicts the equivalent circuit for a cable represented by leak age resistance R and capacitance C.
From phasor diagram,
power factor angle, φ = 90° – δ
or cos φ = cos (90° – δ) = sin δ
