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.

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 ...

The 30th International Conference on Plasma Science, 2003. ICOPS 2003. IEEE Conference Record - Abstracts., 2003
Summary form only given, as follows. In this paper, a novel optical measuring system for the measuring of non-uniform electric field was proposed. The first feasibility investigation on the probe sensor, based on the Pockels cell, has been performed to measure the variation of the electric field due to the corona discharges.

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 ...
