在2017年配电网接地技术与故障处理论坛上，山东理工大学智能电网研究院徐丙垠教授作了题为 “小电流接地还是小电阻接地？——从国际供电会议上的动态谈起”的报告。
In 2017, Professor Xu Pingyuan, Institute of Smart Grid Research, Shandong University of Technology, made a presentation entitled "Small Current Grounding or Small Resistance Grounding?" —— Talk about the developments at the International Power Supply Conference.
徐丙垠教授从巴西配电网谐振接地改造实践、捷克短接故障相消弧试验研究情况、哪种接地方式更有利于人身安全？对配电网接地方式选择的建议等几个方面进行了阐述。
Professor Xu Bingyuan from Brazil distribution network resonance grounding reform practice, Czech short connection fault phase-out test research, which grounding method is more conducive to personal safety? Some suggestions on the selection of grounding mode for distribution network are expounded.
徐丙垠教授认为：
Professor Xu Bingyuan believes that:
1. 国际上有将架空网络接地方式改为谐振接地的趋势；
1. There is a tendency to change the grounding mode of overhead network to resonance grounding in the world.
2. 架空以及架空与电缆混合网络采用小电流接地方式有利于提高供电可靠性与人身安全；
2. The low current grounding mode is beneficial to improve the reliability of power supply and personal safety in overhead and hybrid overhead and cable networks.
3. 配电网接地方式的选择应按国家标准的要求办。避免将架空网络接地方式改为小电阻接地；电容电流小于150A的电缆网络应采用谐振接地。
3. The selection of grounding mode of distribution network should be in accordance with the guangliang.37ix.com.cnxjtuomoji.37ix.com.cnchuganzhi.37ix.com.c gebin.89ix.comzhulvmen.89ix.comlangfang.75ix.cnrequirements of national standards. Avoid changing the grounding mode of overhead network to low resistance grounding; cable network with capacitive current less than 150A should adopt resonant grounding.
