摘要
阐述了中性点不接地电网中单相接地的特点,并分析了用绝缘监视装置和小电流接地选线装置查找故障的利弊,以及目前小电流接地选线技术可靠性差的原因。
The characteristic of single-phase-to-ground fault in isolated neutral power system was briefly explained, and the advantages and disadvantages of insulation monitoring device and the fault line detection of small current grounding system was analyzed. It also analyzes the reasons of technology reliability in the fauh line detection of small current grounding system.
