| Abstract: | The surface of insulators is prone to generate charges under a DC high-voltage for a long time,which has a great impact on insulation performance of the insulators.Surface charges decay by three mechanisms,by volume and surface resistivity of the insulator as well as by neutralization from the gas.To study surface charge decay process on insulators,a set of surface charge measurement device was designed,which could measure the surface charge distribution on insulators in different gases and different air pr... |
