电流互感器基本误差现场检定一次升流方法的研究

The Primary Current Magnification Techniques in the Current Transformer Basic Error Site Verification

高压电能计量装置的准确可靠关系到电厂、电网和用户的巨大经济利益,是各方面都关注的问题。根据有关计量检定规程开展关口电流互感器的基本误差现场检定工作,必须解决一次通流的电源问题。本文针对这一难点问题,总结了传统电流互感器基本误差现场检定时一次升流问题的几种解决方法。

The accuracy and reliability of HV electric energy metering are tightly associated with the huge economic interests of power plants,power system and customers,which are concerned by all. According to national measurement verification regulations,the primary current magnification techniques are the key and difficult points in the current transformer basic error site verification. This paper summarized several techniques to solve this problem.
