摘要
根据小电流接地系统单相接地故障的特点,提出了谐振接地和“S 注入法”选线定位新原理,导出了有关的公式和算法,研制出了相应的装置。
Principle of single phase faulty line identifying and faulty point locating based on syntonic earthing and a novel S's signal injection method is presented according to the characteristic of power system with floating neutral point.The associated discriminant and algorithm are deduced.A corresponding device is developed.
