浅析负荷对电压互感器误差的影响及对策

Analysis of Influence of Load on Error of Voltage Transformer and Measures

电压互感器是电力计量系统中不可缺少的计量、保护设备,它是电力系统安全及关口计量稳定可靠运行的保证。电压互感器的误差对实现计量关口结算和测控保护安全都有非常大的影响。在简述电压互感器检定方法和工作原理的基础上,分析二次负荷对互感器误差的影响和应采取的措施,以降低二次负荷对互感器误差的影响。

Woltage transformer is an indispensable metering protection equipment in power metering system.It is the guarantee of power system safety and stable and reliable operation of gateway metering.The error of voltage transformer has great influence on the settlement of metering gateway and the safety of measurement and control protection.Based on the brief introduction of the verification method and working principle of voltage transformer,this paper analyzes the causes of transformer error caused by secondary load and takes measures to reduc the influence of secondary load on transformer error。
