Development of Transient Electric Field Radiation Simulation Device during Gas Insulation Switch Operation

In gas insulation switch (GIS) substation, secondary devices such as line monitoring are placed in the switching field, and these electronic vulnerable to transient electromagnetic interference caused by operation. order facilitate measurement research of disturbance data under different working conditions, a simulation test device is developed this paper, which can be used simulate GIS substation sensor port A four-channel parallel was designed, main characteristic parameters generated were measured using high-frequency pulse power supply excitation source. The comparison between waveform shows that it good agreement with characteristics, conforms basic characteristics damped oscillation wave, equipment voltage coupling protection measures evaluation assessment method research.
