Abstract

A time-domain model is described for predicting transient bus currents, electromagnetic fields, and cable-coupling effects caused by switching actions in high-voltage substations. Having been validated against measured transient data, the model provides a basis for predicting EMI effects resulting from abnormal switching actions, such as phase-to-ground faults, which are difficult to stage for measurement. From such worst-case estimates, the adequacy of the latest standards for microprocessor-controlled substation protection can be assessed
