Abstract
In medium and high voltage power system networks, electromagnetic transients are inevitable when switching inductive loads such as free-running transformers, induction motors or power compensation coils. The potential occurrence of switching oscillatory overvoltages defines the insulation co-ordination of cable-networks. Harm can be caused to this insulations by either the amplitude or rise time of transients. In this work, the basic phenomena of switching transients are defined and shown with simple power system models. This work also outlines several mitigating methods.
