摘要：
For analysis of the status of oil-paper insulation, the dielectric response method was used to model oil-paper insulation system. Then the dielectric spectroscopy of oil-paper insulation system was tested. And the influence of oil gap on the test results of oil-paper insulation response was discussed. The results showed that the dielectric response method can effectively assess the status of oil-paper insulation, and the influence of oil gap on the test results is less than 10%.
