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

Beiträge aus der Plasmaphysik, 1985
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 ...

Conference Record of the 2008 IEEE International Symposium on Electrical Insulation, 2008
We developed an Ultra high frequency (UHF) partial discharge fixed and portable monitoring systems to prevent a catastrophic failure of gas-insulated switchgears. The system has been tested in the laboratory and on-site for detection of various tested in the laboratory for detection of various UHF PD signals.

JURNAL TEKNIK ELEKTRO, 2022
Penyaluran energi listrik pada Gas Insulated Switchgear (GIS) memiliki dua sumber tenaga, yaitu sumber (AC) bolak balik dan (DC) searah. Salah satu sumber DC yang memiliki peran yang sangat penting adalah baterai 110 VDC. Baterai merupakan suatu sel listrik yang terdapat dua proses elektrokimia, yaitu proses discharging dan proses charging.

In-Situ Measurements of SF6 Leak Rates in Indoor Gas-Insulated Switchgears (GIS)
2001All 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 ...
