2020-10-23GIS is a kind of metal enclosed switchgear. That means, all the equipments of the electrical switchgear are enclosed by gas tight metal enclosure and SF 6 gas is used as insulation between live parts of the equipments and earthed metal enclosure. This type of switchgear, means, and gas insulated switchgear isGet Price
Different types of sensor can be used to measure partial discharges in a gas-insulated substation. Alstom Grid’s latest design uses a conical antenna with a small footprint. Its sensitivity has been tested under laboratory conditions in different calibration cells as well as after having been installed in the switchgear.
