High Voltage Switchgear SF6 Maintenance the years, installations have started to show signs of SF6 breakdown, decomposition and leakage. Given the fact that SF6 is also a potent greenhouse gas, 22,000 times more dangerous to the ozone layer than CO2, power companies are now required by law in the European Union, under the Kyoto Protocol, to monitor vessel top-off and leakage.
Eco-efficient gas-insulated switchgear ABB Power Grids is committed to developing eco-efficient products which reduce use of resources and the effects on the environment throughout their lifecycle. The main insulation gas used in high and medium voltage switchgear is SF6 gas which has several important features. However, SF6 is a known greenhouse gas and while leakage rates ...
Switchgear - Wikipedia switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.

Fingrid will gradually replace SF6 with an insulating gas ...· When the equipment reaches the replacement age and the grid needs the switchgear to be modernised, we aim to install SF6-free switchgear." It is not possible to replace SF6 gas without renewing the entire switchgear. When the switchgear is replaced, reliable suppliers ensure that the SF6 gas is recovered safely and processed appropriately.
Transformer leakage current test can be said that one of the measurement steps in the transformer test, the leakage current test. Its main purpose is to find the insulation strength defects, and even the risk of leakage.
