In this paper,a kind of leakage current collection system for high voltage insulators will be deˉscribed.In this system,a kind of leakage current mutual inductance transducer is designed by the method of electromagnetic inductance and magnetism compensation,therefore accurate measurement of insulator leakage current is achieved.By analysing and processing data,the real-time monitor of insulator status is realized in the system.The result of experiments demonstrates that the system is adaptive to leakage curˉrent that varies in a large scope.In this way,the probability of flashover can be reduced and the reliabiliˉty of power supply system can be improved.
