“…Early methods of mitigating inrush currents (Table 2.4), mostly involved the calculation for the first peak of inrush current [62,63,64]. The proposed method in this work can be implemented using a microcontroller where the program algorithm is written in such way that the switching of capacitors in the network is done any time the current arises above a given value indicating inrush current as well as the starting period.…”

An accurate simulation of magnetizing inrush currents is an important prerequisite for digital protection of power transformers.Generalized analytical expressions have been developed to simulate three-phase inrush currents based on sequence impedance and mutual coupling methods. The digitally simulated waveforms are compared with those obtained experimentally in a laboratory model transformer.There exists a reasonably close agreement between the computed and measured values.
