一种电流互感器误差测量装置及测量方法
摘要：
本发明提供一种电流互感器误差测量装置及测量方法，所述装置包括电源发生器(1)、参考标准器(2)和误差测试仪(3)，所述电源发生器(1)产生大电流交直流合成信号或正弦半波信号，并将产生的信号分别施加给被测电流互感器(4)和参考标准器(2)；所述参考标准器(2)能够将被测大电流信号中的交流和直流成分准确的转换成小电流或小电压信号，小电流或小电压信号作为参考信号输入至误差测试仪(3)；误差测试仪(3)对参考标准器(2)输出的参考信号和被测电流互感器(4)输出的被测信号进行同步采样、转换和计算后得到测量结果。
摘要（英）：

The invention provides an error measurement apparatus and measurement method for a current transformer. The apparatus is composed of a power generator (1), a reference standard device (2) and an error tester (3). The power generator (1) generates a heavy alternating current-direct current synthesis signal or a sinusoidal half-wave signal and applies the generated signal to a tested current transformer (4) and the reference standard device (2); the reference standard device (2) can convert alternating-current and direct-current components in tested heavy current signals into small-current or small-voltage signals accurately, and the small-current or small-voltage signals are used as reference signals and are inputted into the error tester (3); and the error tester (3) carries out synchronous sampling, conversion, and calculation on a reference signal outputted by the reference standard device (2) and a tested signal outputted by the tested current transformer (4) to obtain a measurement result.
