Corona pulses current method is a way which can be used to detect faulty insulators on ground 电晕脉冲电流法是一种地面检测不良绝缘子的方法，但目前应用中其检测的准确度较低。
2.
But its accuracy of detecting is low in application . in this paper we try to find a method based on artificial neural network to improve the accuracy of detecting faulty insulators 本文力图通过大量的实验室和现场数据的分析，发展一种基于人工神经网络的不良绝缘子诊断方法，提高脉冲电流法用于检测不良绝缘子的准确性。
