Gas insulated switchgear (GIS), as the last line defense against short circuits in power system, has a vital significance for ensuring the normal operation of power electronic equipment .Sulfur hexafluoride (SF 6) has been widely applied in GIS as an effective insulating medium due to its excellent chemical stability and high dielectric strength .Author: Haojie Guo, Kai Zheng, Heping Cui, Fusheng Zhang, Jiabing Yu, Lu-Qi Tao, Xiandong Li, Xianping Chen
Transformer - Wikipedia transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer's core, which induces a varying electromotive force across any other coils wound around the same core. . Electrical energy can be transferred between ...
