摘　　要：电子式互感器正逐步投放市场,而目前国内有关电子式互感器的校验尚无统一标准。针对这一情况,通过研究直接法和差值法两种常用的电子式互感器校验方法,利用虚拟仪器技术,设计了一套兼容直接法和差值法的多方式电子式互感器校验仪,同时满足数字输出和模拟输出电子式互感器的校验需求,扩展了仪器的使用范围,提高了系统的可靠性,同时采用频谱泄漏补偿算法,提高了系统的校验精度。With the electronic transformer gradually being launched on the market, there＇s still no unified standard for the domestic electronic transformer calibration. According to this situation, two electronic transformer calibration methods, the direct method and the difference method, are studied. Based on the virtual 4nstrument technology, a novel electronic transformer calibrator compatible with both the direct method and the difference method is designed. This sys- tem meets the calibration requirements for the electronic transformers with digital output or analog output at the same time. It extends the application of thecalibrator and improves its reliability. While using the spectrum leakage compensation algorithm, the calibration accuracy of the system is also enhanced.
