Practical Optical Fiber Current Transformer for Gas Insulated Switchgear
12th International Conference on Optical Fiber Sensors, 1997Here we present practical optical CT using moderate twisted silica optical fiber with temperature-independent coating. It makes use of the Faraday effect and the current is measured by the polarimetric method. The optical CT satisfied all requirements for the gas insulated switchgear (GIS).

Development of 500KV Gas Insulated Switchgear and its Application
IEEE Transactions on Power Apparatus and Systems, 1973The application of Gas Insulated Switchgear (GIS) up to 275kV substations has been proven and the authors have been working jointly on the research and development, with a view of supplying GIS for the 500kV trunk systems in the near future. To demonstrate the reliability and intearity of GIS.

Measurement of TEV of 1000kV UHV gas insulated switchgear
2015 7th Asia-Pacific Conference on Environmental Electromagnetics (CEEM), 2015The paper describes problems with EMC of monitoring instrument in 1000kV gas insulated switchgear (GIS), due to transient enclosure voltage (TEV) produced during disconnector switching. Measuring method of TEV has been studied, including the choice of a reference ground point, the discussing about unique of scalar potential difference, and the method ...

Development of intelligent gas insulated switchgear using electronic technology
2003 IEEE PES Transmission and Distribution Conference and Exposition (IEEE Cat. No.03CH37495), 2004The digital control panel and electronic instrument based microprocessor techniques for GIS (gas insulated switchgear) has been developed. Extensive electronic upgrading including digital control mechanisms permits the entire system to be made more compact compared to conventional systems using electromagnetic relays and magnetic core, and enables ...

Partial Discharge and its Application to Gas Insulated Switchgear
2004Higher reliability is demanded with gas insulated apparatuses such as gas insulated switchgear (GIS) and gas insulated circuit breaker (GCB). Since gas insulated apparatuses are sealed structures, it is difficult to find internal defects from outside. Therefore, development of preventive maintenance techniques is necessary for GIS to prevent failures ...
