摘　　要：在涉及到中阻抗母线保护装置的调试时,若不注意"中阻抗母差保护的三次侧电流严禁接地"这一原则,将很容易导致严重后果。本文就一起试验时发生的故障来分析该问题,并提出解决办法。When it is involved with debugging of medium impedance bus protection unit, severe aftereffect will be easily induced if people fail to attach importance to principle of trictly forbidding grounding of three-time side current with medium impedance bus differential protection This paper analyzes this problem using a failure occurred during a test, and puts forward resolution.

关 键 词：中阻抗 母差保护 调试 故障分析
