| Abstract: | The factors of insulation resistance test which used DC comparative method are analyzed, and a model of uncertainty and achieved a comprehensive assessment about the uncertainty of the test is established. The authors first- ly utilized curve fitting manner to obtain temperature coefficient, and proposed some details for reducing the uncertainty of insulation resistance test. This work is a useful guide for insulation resistance test. |
