| Abstract: | The gas insulated transformer station is more and more used in electric power system. GIS volage class is increased to make isolators,earthing switches and circuit breakers which cause fast transient overvoltage to be serious and to harm operation safety. The paper analyzes the mechanism to the fast transient overvoltage and sets up equivalent pattern and numerical calculation. The research to GIS internal fast transient overvoltage has important meaning for electrical engineering. |
