Verification of the seismic resistance of gas-insulated switchgear (GIS)

IEEE Transactions on Power Delivery, 1993
A brief introduction into the background of seismic requirements is given. The test procedures are described, demonstrating the capability of gas insulated switchgear (GIS) to withstand seismic stresses up to highest ground accelerations of 0.75 g. The verification methods for checking the test object after test are described.

Discharges from moving particles in GIS [gas-insulated switchgear]

IEEE Transactions on Power Delivery, 1998
The study of the motion of moving metallic particles in GIS requires a good knowledge of the carried charge of the particle. In this paper, measurements of the charging process of a moving particle, performed in a realistic single-phase GIS, are presented.

Controlled Voltage Breakdown in Disconnector Contact System for VFTO Mitigation in Gas-Insulated Switchgear (GIS)

IEEE Transactions on Power Delivery, 2017
Several methods have been proposed and investigated so far on mitigation of very fast transient overvoltages (VFTO) in gas-insulated switchgear (GIS). The state-of-the-art methods are primarily based on dissipation of the energy associated with electromagnetic waves that the VFTO originate from and are composed of.

Determination of Type of Partial Discharge in Cubicle-Type Gas Insulated Switchgear (C-GIS) using Artificial Neural Network

2018 Condition Monitoring and Diagnosis (CMD), 2018
Partial discharge (PD) measurement is performed as one of diagnostic tool for condition monitoring in cubicle-type gas insulated switchgear (C-GIS). This paper presents artificial neural network (ANN) to identify the type of PD occurring in C-GIS. PD measurement results obtained from C-GIS in a field were fed to the ANN as input parameters to determine

Vibration Fault On-site Dection of Gas-insulated Switchgear (GIS) Equipment Based on Ultrasound and Ultra-high Frequency Measurement Method

2019 IEEE Sustainable Power and Energy Conference (iSPEC), 2019
At present, GIS equipment (gas insulated switchgear) is more and more popular in power system, and the detection of GIS faults is mainly aimed at discharging faults. But more and more phenomena show that mechanical faults can not be ignored. In this paper, by analyzing a case of GIS field detection based on ultrasonic and ultrahigh frequency (UHF ...
