In order to improve the adaptability of cross-linked polyethylene cables in power systems,it is necessary to conduct on-site AC withstand voltage tests after completing the installation of cross-linked polyethylene cables to test the comprehensive performance of the cables.Starting from the working principle of the variable frequency series resonance test method,the application calculation and analysis of series parallel resonance are carried out,and finally the precautions for the test are explained,aiming to provide reference for relevant personnel.
