为补充IEC 60076-3的要求，对电力变压器雷电和开关脉冲试验的现有程序提供指导和解释性意见。也通常适用于电抗器的测试（见IEC 60289）， 如有需要，应说明电力变压器程序的修改。 提供了有关波形、测试电路（包括测试连接、接地实践、故障检测方法、测试程序、测量技术和结果解释）的信息。

Gives guidance and explanatory comments on the existing procedures for lightning and switching impulse testing of power transformers to supplement the requirements of IEC 60076-3. Also generally applicable to the testing of reactors (see IEC 60289), modifications to power transformer procedures being indicated where required. Information is given on waveshapes, test circuits including test connections, earthing practices, failure detection methods, test procedures, measuring techniques and interpretation of results.
