3.2 考虑到本(ben)标准将指导运(yun)行使用单位的维护行为，在标准中增(zeng)加(jia)了投运(yun)前检验(yan)和定期检验(yan)两项内容。

3.3 在“术语(yu)和定义(yi)”中，增加了单相接(jie)地、永久接(jie)地、瞬(shun)间(jian)接(jie)地等 7 项(xiang)同接(jie)地选(xuan)线相关(guan)的术语(yu)定义(yi)。

3.4 在(zai)“技术要(yao)求”中，考(kao)虑(lv)到目前(qian)新的维(wei)护(hu)工作需(xu)要(yao)，在(zai)“基本功(gong)能(neng)要(yao)求”中增加了故障录波和(he)远程维(wei)护(hu)功(gong)能(neng)。
