摘　　要：目前国内电力企业等多个单位广泛开展变压器容量的测试工作,大量使用变压器容量测试仪等设备,但是目前缺少针对变压器容量测试仪的校准方法,本文分析了变压器容量测试仪的工作原理,结合目前的实际工作情况,根据实际工作和现有的相关规程规定,分别用标准源发生器法和直接比较法两种方法,给出了校准"变压器容量测试仪"的方法,该两种校准方法都能够对变压器容量测试仪的技术指标进行准确的判定,具有较高的实用价值,为校准变压器容量测试仪提供了一种思路。Recently, domestic power enterprises and other units carry out extensive testing of transformer capacity, use transformer capacity tester and other equipment greatly, but the calibration method for capacity of transformer is short. This paper analyzes the principle of capacity of the transformer tester, combined with the current practical work. According to the practical work and the existing rules, it used two methods to calibrate the ＂capacitor tester of transformer＂ respectively. The two methods both can accurately identify the technical indicators of the tester and have high practical value, providing a new idea to calibrate the tester.
