电子式互感器现场误差校准装置的研制

随着技术的进步,以光电式互感器为代表的新一代电子式互感器正逐步投放市场.电子式互感器的二次输出与传统互感器的二次输出不同,分为数字输出和模拟输出两种.对数字输出的电子式互感器,国际电工委员会做出了相应的标准化工作.本文所实现的装置能兼顾对数字输出和模拟输出的电子式电流互感器和电子式电压互感器进行校准;采用频谱泄漏补偿算法,对被测信号的频率波动不敏感.

Development of the Field Error Calibrator Equipment for Electronic Transformers

As the rapid development of electronic transformers in electrical substation,a new kind of calibrator equipment for the field error calibration of the electronic transformers is needed.In this paper,an equipment for the calibration of both electronic current transformers and electronic voltage transformers is presented.A special method of the compensation of spectral leakage is used so that the measured signal is insensitive to the fluctuation of signal frequency.The principle of operation is described and ...
