并通过电路仿真及频率波动对相位影响的研究

研制了氧化锌避雷器在线监测装置现场计量标准。试验结果表明文中提出的方法及计量标准可对准确度为1%及以上金属氧化物避雷器在线监测装置展开现场校准试验。

Abstract

Aiming at the problem that the zinc oxide lightning arrester on-site monitoring device is difficult to carry out on-site live calibration

an on-site calibration method with injecting standard signals after emptying leakage current is presented.The corresponding characteristic quantities of the calibration are analyzed

and the measurement standard for on-site monitoring device of zinc oxide arrester is proposed through circuit simulation and analysis on effect of frequency fluctuation on phase fluctuation.Experimental results show that the proposed method and measurement standard can be used for on-site calibration of MOA on-site monitoring device with accuracy of 1% or higher.
