电力系统计量中互感器误差的现场测试技术探究

Site Test Technology of Mutual Inductor Error in Measurement of Electrical Power System

电能计量装置是由电能表互感器和互感器的二次回路组成的,对电能计量装置进行定期检定可以为供电及用电各方提供保障。电能结算是通过电能计算装置实现的,但它总是不可避免地存在一定的误差,从而直接影响供电以及用电各方的权益。因此,要为减少误差而采取一些措施,现场测试技术应运而生。论文将传统的计量方法和现场测试技术进行对比,并分析了现场测试技术的发展前景,以供参考。

The electric energy metering device is composed of an electric energy meter mutual inductor and secondary circuit of mutual inductor, periodic verification of electric power measurement devices can provide guarantee for power supply and utilization. The energy calculation is realized by electric energy metering device, there is a certain error inevitably, then directly effects the profit of power supply and utilization. So it is necessary to take some measures to minimize the error, and the onsite test technology emerged.This paper compares the traditional measurement method with field test technology, and analyzes the development prospect of field measurement technology ,for reference.
