Abstract

It is known that energising power transformers can produce large inrush currents due to magnetic core saturation. This paper shows that core saturation can also be caused by the switching action of thyristors which are used either to 'soft energise' a transformer or to 'soft start' an induction motor supplied via a step-up/step-down transformer. A set of measurements is presented to illustrate the transient phenomena. The transient process is analysed and the case to be avoided in practice is identified for the motor soft starting system.
