Electromagnetic Transients in High-Voltage Power Stations

Abstract

Line faults and switching events in high-voltage power stations produce transient fields that are potential sources of electromagnetic interference. A general discussion of the transient fields and their measurement is presented. The hardware and software comprising a complete measurement system are described. Specific examples of experimental data are given for transient fields produced by the operation of dis­ connect switches and circuit breakers. The paper con­ cludes with a discussion of susceptibility tests that could be applied to electronic equipment that is intended for use within a power station.
