rameshwari Posted November 10, 2003 Author Report Share Posted November 10, 2003 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.;q Link to comment Share on other sites More sharing options...
marke Posted November 13, 2003 Report Share Posted November 13, 2003 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.

jhun Posted February 6, 2004 Report Share Posted February 6, 2004 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 Link to comment Share on other sites More sharing options...
