Development of 800 kV gas-insulated switchgear

IEEE Transactions on Power Delivery, 1992
An 800 kV gas-insulated switchgear, with a capacity level recognized as the largest in the world, was developed as the first development of UHV gas-insulated switchgear, and good results were obtained in the type tests for this switchgear. With the gas circuit breaker and the disconnector used in this gas-insulated switchgear, tests on a scale ...

Coupling Devices for the Detection of Partial Discharges in Gas-insulated Switchgear

IEEE Power Engineering Review, 1981
Partial discharge in gas-insulated 8witchgear is indicative of serious malfunction and, otten, imminent failure. Partial discharge magnitudes range from zero to about a microcoulomb per pulse. Sources of partial discharge can be detected acoustically, electromagnetically or through gas analysis.

Contact‐failure phenomena and their development in gas‐insulated switchgear

Electrical Engineering in Japan, 1993
AbstractTo explain contact failure phenomena and their development in the gas‐insulated switchgear (GIS). tests were conducted by simulating abnormal current‐carrying conditions using an actual 300‐kV, 2000‐A GIS.This paper describes the process observed. ranging from contact failures to ground faults, deteriorative phenomena and some detection methods

Capacitive sensor for the measurement of transients in gas-insulated switchgears

2009 IEEE Conference on Electrical Insulation and Dielectric Phenomena, 2009
A capacitive sensor has been developed for the measurements of very fast transient over-voltages (VFTO) in GIS. Step response measurement was performed on the sensor. It is shown from the test that the settling time is less than 20 ns and the response time is less than 2ns, suitable to the IEC1321-1.

On the management of metallic particle contamination in gas insulated switchgear

IEEE Transactions on Dielectrics and Electrical Insulation, 2017
Electrical insulation performance of compressed gas insulated switchgear (GIS) is adversely affected by metallic particle contaminants with a loss of up to 90% of the gas dielectric strength. Such particles play a crucial role in determining the system insulation integrity. Coating of the inside surface of GIS enclosures with a dielectric material such
