WebAll the core flux Φ also links the secondary coil (no leakage flux) causing in it an induced emf of It is easy to see that e 1 and e 2 are in phase. This is so indicated by Phasor Diagram of Transformer on No Load in Fig. 3.6 where E 1 and E 2 are the corresponding phasors or in terms of the rms values. As the secondary is open-circuited, its ...

Phasor Diagrams and Phasor Algebra used in AC Circuits

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. WebPhasor Diagrams can be used to represent two or more stationary sinusoidal quantities at any instant in time.
