Two planar antennas for detection of partial discharge in gas-insulated switchgear (GIS)
2015 IEEE International Conference on Communication, Networks and Satellite (COMNESTAT), 2015The detection of partial discharge in GIS plays a pivotal role in preventing and mitigating severe operational failure and damage in insulation elements. Partial discharge progressively degrades the insulating medium and, as a result electrical breakdown can occur in GIS.

Emerging Technologies in High Voltage Gas Insulated Switchgear-Clean Air GIS and NCIT
2019 International Conference on High Voltage Engineering and Technology (ICHVET), 2019Presently, the Gas insulated switchgears (GIS) are used extensively in the power transmission and distribution systems worldwide. The compactness and durability of Gas insulated switchgear is the key reason for their popularity. The compactness is mainly because of presence of SF6 gas, having the best characteristics as an insulating and quenching ...

Ultra-High Frequency (UHF) Based Partial Discharge Measurement in Gas Insulated Switchgear (GIS)
2019 International Conference on High Voltage Engineering and Technology (ICHVET), 2019Gas Insulated Substations (GIS) offer significant advantages over conventional Air Insulated Substations (AIS) on account of reduced space and operational efficiency. Partial discharge (PD) measurement is one of the important test in GIS to ensure its reliability during service and also to reveal defects at incipient levels. One of the methods employed

AbstractGIS for operation voltages ≧ 245 kV can be tested with oscillating impulse voltages on site advantageously, because this H. V. test can be performed with easily mountable impulse generators. The IEC recommendation for on‐site testing of GIS which is now under discussion doesn't fix the time parameters of the oscillating impulse voltages, but ...
