外施电压法对互感器伏安特性测试仪的量值溯源

Tracing the measurement value of transformer volt ampere characteristic tester by applying voltage outside

互感器伏安特性测试仪主要是对互感器的伏安特性进行试验的专用仪器,是继电保护测试和高压绝缘测试的专业检测仪器[1]。此类仪器,各个厂家的名称不同,参数不一,但是,伏安特性作为其基本功能,是此类仪器的标准配置。为此,本文从电磁计量专业出发,选取其中电压部分功能进行校准分析,从而达到量值溯源的目的。

the transformer volt ampere characteristic tester is a special instrument for testing the transformer volt ampere characteristic.It is a professional testing instrument for relay protection test and high voltage insulation test.This kind of instrument has different names and parameters from different manufacturers.However,as its basic function,volt ampere characteristic is the standard configuration of this kind of instrument.Therefore,this paper starts from the electromagnetic measurement specialty,selects the voltage part of the function for calibration analysis,so as to achieve the purpose of traceability.
