Blue gas-insulated switchgear | References | Siemens ... blue GIS 8VN1 from Siemens is an innovative, compact switchgear product. 8VN1 doesn't use Sulfur hexafluoride (SF6 gas) or other fluorine gases as an insulating and interrupting medium. Instead of greenhouse gases, it uses compressed synthetic air (so called clean air) technology to provide insulation between live parts and the earthed metal housing.[email protected]

Current Transformer : Construction, Working, Types and Its ... Transformer Device Working Principle. The working principle of the current transformer is somewhat different when we compare it with a normal voltage transformer. Similar to the voltage transformer, it includes two windings. Whenever AC supplies throughout the primary winding, then alternating magnetic flux can be generated, then AC will be induced within the secondary winding.
