Abstract

The potential threat that electromagnetic disturbances generated during disconnector switching poses to substation-based control, protection and communication equipment has been raised in previously published literature. A better understanding of the coupling mechanisms involved can assist engineers in designing systems that are immune to these disturbances. An experiment designed to evaluate inductive, capacitive and conductive interference in the context of coupled unwanted common mode currents is described
