Hello rameshwari
Welcome to the forum.
Can you please expand on what you mean by hf circuit?
Best regards,

hi!
by hf circuit i meant high frequency circuit.
actually i am working on a high frequency induction heating system. i want to measure the power factor of the system. so i wanted some details about how to measure pf in case of hf circuit.

Hello rameshwari
It depends on the frequency that you are operating at, but you could measure the power factor (angular displacement) with an oscilloscope) unless the frequency it too high.

power factor is = kw/kva.
take the actual inline current. and compare to kw rating.
inline current mutiply by 1.73 if you load is three phase and multiply by the voltage, devided by 1000= your kva
