摘要

介绍一种应用单片计算机构成的MOA避雷器阻性电流在线测试仪

用实验室和现场测试数据与LCD-4型仪器进行了全面比较。结果表明:它在信号采集

处理和抗电磁干扰能力方面有独特之处。同时

测量的可靠性高

稳定性好

数据的准确性与LCD-4型仪器相当

能较灵敏地反映避雷器中的高次谐波分量

适合于有氧化锌避雷器的基层单位使用。

Abstract

A MOA resistive current on-line measuring instrument using the chip computer is described.Complete comparison between this one and type LCD-4 one is made through the experiments in the lab and in the field.Results show that it is distinctive in aspects of signal sampling

processing and anti-EM-interference.The instrument has high relibility and good stability

and can reflect sensitively higher harmonic components in MOA.Its accuracy rivals type LCD-4 instrument.It’s suitable to common MOA users.
