In this paper, a kind of polluted leakage current acquisition system for high voltage insulators is described. In this system, a kind of leakage current mutual inductance transducer is designed by the method of electromagnetic inductance and magnetic compensation, thus accurate measurement of insulator leakage current is achieved. Through data analysis and data processing, the real-time monitor of insulator status is realized in the system. The result of experiments demonstrates that the system is adaptive to leakage current which varies in a large scope. In this way, the probability of flashover can be reduced and the reliability of power supply system can be improved.
