摘　　要：互感器校验装置是用于检定电压互感器与电流互感器的专用设备,随着现代工业的发展,对互感器校验仪的要求也逐渐提升,互感器校验仪也随之不断发展。主要介绍了互感器的校验方法;概述了互感器校验仪从手动到自动,高智能化的发展,并根据其发展对互感器校验仪进行了分类,简要分析了各种取差、测差电路以及相关产品,指出互感器校验仪的最新发展方向。Transformer calibrator is the special verifying attachment for voltage and current transformers. With the development of modem industry, the demand for transformer calibrator becomes higher and higher, and so that calibrators have their development. This paper mainly introduces the methods of transformer＇s verification, summarizes many kinds of manual and automatic transformer calibrators and new microprocessor-based current transformer calibrator＇s generation circuit of signals and testing circuit by collecting lots of new information. By comparing these methods with each other, it concludes the best calibrator system based on the development platform of virtual instrument, which possesses multi-functions can speed up the development of novel transformer.
