漏电保护器测试仪的几种校准方法

Leakage protection tester of several calibration method

文章介绍了漏电保护器的工作原理,对漏电保护器测试仪动作电、流跳闸时间和回路阻抗等主要参数,分析几种校准方法,并对各种方法的优缺点作了评价,同时还简单地介绍了各测试参数的不确定度的来源和评定结果。

This paper introduces the working principle of leakage protection, protection against leakage tester operating current, trip time, loop impedance analysis of several key parameters of the calibration method, and the advantages and disadvantages of various calibration methods were evaluated. This paper also gives a brief introduction of various test parameters of the sources of uncertainty and evaluation results.
