Research on Integral Error Calibration Technology of High Voltage Power Metering Device and Its Application

为解决现有高压电能计量装置的整体误差校验现场工作,提出了一种高压计量整体误差现场校验装置,将电压互感器、电流互感器、二次压降及低压电能表作为一个被测试的整体,通过装置输出的高压大电流模拟高压电能计量装置的实际运行工况,实现计量误差的现场校验。

To solve the field calibration of integral error ~or existing high voltage power metering device, this paper puts forward the field calibration device of high voltage metering integral error. The calibration device takes voltage transformers, current transformers, secondary voltage drop and low voltage power meter as a whole test object. The calibration device can output high voltage and high current to simulate actual operating conditions of high voltage power metering device. Therefore, it achieves the field calibration of measurement error.
