Measurement and Characteristic Analysis of Transient Radiated Switching E-Field of GIS

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

“…Transient electromagnetic field generated during switching operation is one of the important sources of electromagnetic interference in substations [10]. The characteristics of the transient electric field generated by the switching operation of the substation can be understood by field measurement, including the characteristics of the transient field in time domain and frequency domain [11,12]. It is particularly important for the device to be able to simulate the transient radiation electric field in the field, so it is urgent to try to produce a miniaturized device that can simulate the transient radiation electric field in the switching process of GIS.…”

Research on measurement technology of action characteristics of double-ended grounding switch based on flexible sensing

“…Unlike the conventional outdoor switch, there is no open bus, isolating switch, grounding switch, etc. When testing the action characteristics of the GIS combined electrical circuit breakers [6], we cannot take signals directly from both sides of the circuit breaker. However, at present, the traditional test methods of the circuit breaker operating characteristic test instruments all adopt the way that one end of the circuit breaker is shortcircuited to the ground, and the other end is connected to a signal line for sampling to measure the operating characteristic parameters [7,8].…”
