Experimental Research on Strong Transient Electromagnetic Interference in Substation

EasyChair Preprint 5503

Abstract

This paper proposes an experimental method to study strong transient electromagnetic interference in substation. A circuit breaker is used to control the turn-on and -off of the sphere gap arc to generate continuous multi-pulses to simulate the process of opening and closing strong transient electromagnetic interference of 330kV Air Insulated Switchgear (AIS) and Gas Insulated Switchgear (GIS). The electromagnetic interference is measured under different voltage levels, different load conditions and different positions, which is used to evaluate the immunity characteristics of the secondary equipment. The experimental method in this paper can also be applied for the electromagnetic compatibility performance evalulation of electronic transformer, where the isolation switch is used to simulate the electromagnetic interference source.

Keyphrases: AIS, Electromagnetic Interference, GIS, Isolation Switch
