A LSTM Line Selection Method of Single-phase Ground Fault Based on Big-data Platform
2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES), 2021Due to the complex structure of the distribution network, a large number of power supply branches, and various neutral grounding modes, there is a problem with inaccurate fault line selection results.

Research and improvement of single-phase ground fault compensation in distribution network
2021 IEEE International Conference on Computer Science, Electronic Information Engineering and Intelligent Control Technology (CEI), 2021The power distribution system generally adopts neutral non-effective grounding. Most grid faults are single-line to ground (SLG) faults. As the SLG faults are difficult to monitor online, they severely threaten human health and lives and damage power ...

Detection of Single-Phase to Ground Faults in Low-Resistance Grounded MV Systems
IEEE Transactions on Power Delivery, 2021The Conventional zero-sequence (ZS) overcurrent protection method exhibits poor performance for single-phase to ground faults (SPGFs) with high impedance in low-resistance grounded systems (LRGSs), a type of medium-voltage (MV) distribution system. Hence, in this study, a novel SPGF detection methodology, designed specifically for LRGSs, is proposed ...

Ground-fault loop impedance calculations in single-phase systems
49th IEEE/IAS Industrial & Commercial Power Systems Technical Conference, 2013Protection against electric shock in low-voltage installations by automatic disconnection of the supply must be provided in compliance with applicable national or international standards. Such regulations (e.g. National Electrical Code in the U.S., IEC 60364, BS 7671 in the U.K., etc.) take into account the earthing system of the installation, such as ...

A new single-phase-to-ground fault-detecting relay
Electrical Engineering, 1942In the application of differential relays the need for a supervising relay which will detect the existence of a single-phase-to-ground fault condition to the exclusion of all others has frequently arisen. Heretofore, the only scheme available has been to utilize a relay energized by zero-sequence quantities. Generally, the relay has been energized by a
