If a purely inductive circuit is excited with an AC source, a transient occurs before reaching the steady state 90 ophase shift i.e. the current takes some time to shift the phase depending on the switching instant. Is there any such transient in CT?? Suppose the primary circuit is initially off and I mounted a CT on the line. Then if I switched on the power supply, what will be the nature of this transient waveform of secondary current?? How does the primary current come to know how much of it should be the magnetizing current?? Or am I getting it wrong at all?? Thanks in advance..
