Voltage Surge Wave Propagation in Transformer Winding

Original language description

This paper deals with very fast transient phenomena in the transformer winding. A one-phase transformer is considered and the time-space voltage distribution in a transformer winding is investigated. The winding model is created as a circuit with distributed parameters. Resistance, inductance (including turn-to-turn inductive coupling), conductance and both, the turn-to-turn capacitance and the turn-to-iron core capacitance are considered. Parameters could be space varying along a winding length. The solution is done numerically in the time-space domain and various approximations of derivatives have been tested. The inner resistance of a various input voltage source is implemented. The influence of a various rate of rise of input signals on the voltagedistribution was observed and various types of the load were considered.
