摘　　要：灯具泄漏电流测试线路中隔离测试变压器次级接地问题直接影响着测试结果的准确性。本文用试验数据和电路理论,分析了泄漏电流测试线路中隔离测试变压器次级接地的必要性,为灯具制造商与仪器制造商以及质检机构提供参考,从而为贯彻GB7000.1-2007《灯具第1部分:一般要求与试验》标准提供指南。The earthing of secondary circuit of an isolating test transformer on the circuit for luminaire leakage current test strongly influences the accuracy of test results. Depending on the test data and the circuit theory, the article expatiates the necessity of the earthing of secondary circuit of isolating test transformer on leakage current test, to give reference for manufacturers and test houses, and provides the guidance for carrying out the GB 7000.1 -2007 Luminaries-Part 1 ：General requirements and tests.
