Since the flux φ is common to both the windings of a transformer, it is taken as the … WebTransformer Equivalent Circuit in Phasor Form In phasor form, the transformer equivalent circuit takes the form shown in Fig.3. The reactances are derived by multiplying the inductances by the radian frequencyω = 2πf ω = 2 π f, where f is the frequency.
WebI notice that in transformer the secondary side current & current referred to as primary are 180 degree out of phase from each other. But why it is so, I don't know.I did some theoretical analysis on this topic but no phasor analysis(why 180 degree). So, please give me suggestions. I also thought a phasor analysis but I need 10 reputations.
