【Abstract】 In this paper a on line test method for equipment with capacitive insulation construction (bush, instrument transformer, coupling capacitor etc.)is briefly introduced, and some key factors on field which is necessary to pay attention are analyzed. It is confirmed that only the factors as surface pollution, electromagnetic interference and so on are eliminated, a correct test result can be obtained.更多还原
