摘　　要：分析基于静电感应原理的非接触过电压传感器的原理．进行了基于非接触式感应原理的过电压在线监测的研究，介绍了过电压监测系统各部分的组成以及实验平台，在此基础上做了大量工频电压以及雷电过电压的实验。实验结果表明：通过测量非接触传感器上的电压，再乘以转换矩阵，可以较准确地得到被监测电压，实验结果验证了非接触测量理论的可行性与可靠性。The article analyzed the principle of contactless inductor based on Electrostatic induction, and then do some research on over-voltage monitoring based on contactless induction, describing the structure for this device. At last they do a lot of frequency experiments and lighting over-voltage experiments. The experiments result showed that： by measuring the voltage on the contactless sensors, then multiply the transform matrix, the real voltage can be obtained. The experiments result tested the feasibility and reliability of the contactless measure theory.
