hello Everyone
The magnetizing current gotten from the simulation of a three-phase transformer in flux 3D, is it peak value of current or rms value of current?
Hi Harmony Peter,In 3D example of three-phase transformer, the imposed current in conductors for short circuit test, is RMS value of current. Please refer to screenshots of HV and LV circuits below. Also, attaching the document for your reference.
Thank You,Charishma Modem
Hello
Thanks for the reply, but what I mean is that in the open circuit test the magnetizing current gotten after simulation, is it peak value of current or Rms value of current?
Also in the simulation of open circuit test, if I want to use current instead of the rated rms primary voltage, should I use the rated rms primary current(655A) or I have to find the no-load current and if so is there a way to do that ?
Thank you very much

Hi Harmony peter,
The Mod(I(B_HV_A) gives absolute value of current at rated voltage, Mod(I(B_HV_A)/sqrt(2) gives Rms value. The best way of doing the no load test is by applying the voltage. Usually no load current is quantity obtained from no-load test. The no-load current is small percentage of the rated current
