Basic transformer parameters and construction

By Faraday's Law of induction shown in eq.farady single phase pole mounted transformers EMFs vary according to the derivative of flux with respect to time.The ideal transformer's core behaves linearly with time for any non-zero frequency.Flux in a real transformer's core ehaves non-linearly in relation to magnetization current as the instantaneous flux increases beyond a finite linear range resulting in magnetic saturation associated with increasingly large magnetizing current, which eventually leads to farady transformer 400kva overheating.
