In a transformer the flux phasor

WebAn ideal transformer comprises two resistanceless coils embracing a common magnetic circuit of infinite permeability and zero core loss (Figure 2.18).The coils produce no leakage flux: i.e. the whole flux of the magnetic circuit completely links both coils. When the primary coil is energised by an alternating voltage V 1, a corresponding flux of peak value Φ m is … WebThe flux in the core above the rated capacity cause saturation of the magnetic core which leads to complete failure of current transformer.

WebMay 3, 2024 · The phasor diagram of an ideal transformer under no load condition is shown below. Since the core loss of transformer is zero, the magnetizing current I m is in phase with the core flux (ø). This can also be understood as flux is directly proportional to mmf (N 1 I m ), hence both the flux and magnetizing current are in phase. 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.
