what do you mean by power factor ? in new view
Answers were Sorted based on User's Feedback
It is the value of cosine angle between voltage and current due to inductive load (legging power factor) i.e the the value of cos 36 degree is 0.8 ( 0.8 cos fi ),cos 26 degree is 0.9 approx.(0.9 cos fi) and so on. It is also calculate by
True power/Apparent power,Resistance/Impedance or conductance/Admittance.here current leg behind voltage And in capacitive load that angle is minimized i.e improving the power factor.

Answer / rishikesh borse
the ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage. The difference between the two is caused by reactance in the circuit and represents power that does no useful work.

3 Answers Infosys, NTPC, Suzlon,
For polarity test on a 11/3.3kV 2.5MVA delta-star Unit Auxiliary transformer,415V 3-phase supply was applied at the HV. Connection between Aa was made with a 2.5mm cable. As soon as power was switched on the cable caught fire and burnt. This test was then abandoned. It is noteworthy to say that a similar cable was also used in a similar transformer for the same. The cable did not burn and test was successfully completed with good result. What is wrong? Please, help me out.
