“…In this way, one can divide a group of winding in the following way. Half of the capacitance between coils is added to the edges of the coils [19]- [21]. Then, it is assumed that there is an equipotential line in the middle of the coil, so that the capacitance between coils can be added as a cross-over capacitance at each coil with a value equal to the half of the value of the total capacitance.…”

INTRODUCTION IT IS well known that during switching highly inductive loads like transformers and motors, under specific conditions, multiple restrikes in the circuit breaker can occur. Multiple restrikes are fast voltage surges which proceed along the cable and reach transformer or motor terminals. Because of different surge impedances at terminals, a wave reflection and absorption takes place. Voltage oscillations which proceed toward windings are continuously superposed by new voltage waves from new upcoming surges. Hence, voltage waveforms along the transformer winding within a particular time interval can have very different amplitude and rate of rise. Their oscillations contain a broad frequency range which can be from a few kilohertz up to a few megahertz. These are unwanted phenomena [15]. This model is based on the measured frequency admittance matrix of the transformer, the elements of which are admittances measured from any provided measuring point in the transformer windings [16]. The advantage o...

“…In Refs. [3,4], the lumped parameter analysis was used for transformer modelling, and [5,6] deal with the modelling of transformer based on the well-known Rabins method. It was also shown that transformer can be modelled by considering the windings or group of windings as transmission lines [7,8].…”
