基于降低计量装置综合误差的设备选型研究

Research on Equipment Selection to Reduce Integrated Error of Metering Device

在实际运行中,整体电能计量装置存在着综合误差,这个综合误差是由电能表本身的误差,电压、电流互感器的合成误差与电压互感器二次回路压降引起的误差三部分组成。设备选型技术是实践中总结出来的降低电能计量装置综合误差的有效方法,通过该技术的广泛应用,有效地控制了计量装置的综合误差,进一步提升了计量专业精益化管理水平,确保了电能的公平交易。

In actual operation, there is integrated error on electrical energy metering device. The integrated error is attributed to the error of the meter itself, synthesis error of voltage and current transformer and the error caused by voltage transformer secondary circuit voltage drop. The equipment selection technology plays a key role in reducing the integrated error of electrical energy metering device. The implementation of the technology will effectively control integrated error of energy metering device and improve the management of energy measurement to ensure fair dealing of electrical energy.
