In-Situ Measurements of SF6 Leak Rates in Indoor Gas-Insulated Switchgears (GIS)

2001
All SF6-insulated equipment leaks to some degree. These losses of SF6 gas are usually low and usually less than 2% of the whole gas content of typical GIS. They occur slowly and almost undetected for many years, until a low gas pressure alarm sounds. Over the last fifteen years, manufacturers have continuously improve the gas tightness of their metal ...

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 ...

Quality Analysis and Lifetime Prediction of SF₆ in High Voltage Gas Insulated Switchgear (GIS) at CSW Bulungan

2019 IEEE International Conference on Innovative Research and Development (ICIRD), 2019
This paper represents the relation between moisture content and dew point of SF 6 gas using the Magnus method. The method shows that the main circuit breaker in the high voltage gas insulated switchgear (HVGIS) is the most fragile compartment. The relationship of dew point to moisture content of SF 6 in HVGIS is linear with the rate of change ...
