Abstract: Research on corona loss in UHV transmission lines holds significant implications for rational control of line losses and enhancement of environmental protection level. In this context, the technical route integrating simulation experiments and theoretical calculations is adopted to study the equivalent measurement method of corona loss of UHV transmission lines based on corona cage test device. Comparative analyses between actual sample measurements and equivalent test results validate the accuracy of corona loss values derived from equivalent methods under both dry and rain-wetting conditions for single conductor and 1 000 kV UHV AC test lines. The findings conclusively demonstrate the validity of corona cage-based equivalent measurement approaches for UHV transmission line corona loss assessment.

Key words: corona loss, corona cage, ultra-high voltage(UHV), bundled conductor, equivalent measurement
