gis substation sensor HV and LV equipment in China

In substation 1 the high voltage tests were performed by means of an encapsulated test transformer and for PD measurement the UHF method was applied using mobile window sensors [9]. In substation 2 a resonant test circuit was used for HV testing and the PD measurements were carried by means of the conventional method using an encapsulated coupling capacitor for coupling out the PD signals.

  • Major components you can spot while looking at HV/EHV GIS

    Apr 06, 2021 · Gas-insulated switchgear (GIS) is a piece of high voltage equipment that is being constantly developed day by day. The basics of GIS technology is more or less the same, but everything else under the hood is improved a lot comparing to just a few years ago. This article explains major GIS components and their characteristics.

  • Gas-Insulated Substations - GIS

    A gas-insulated substation (GIS) uses a superior dielectric gas, sf6 gas, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in insulating gas gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what insulating gas can do in centimeters.
