A New Arc Suppression Method for Single-phase Grounding Fault in Distribution Network
2022 7th Asia Conference on Power and Electrical Engineering (ACPEE), 2022Single-phase grounding faults occur frequently in distribution network. Extinguishing the arc caused by faults quickly can improve the reliability of power supply and the stability of the system.

Single-phase grounding fault location based on Synchrosqueezing S-transform (CICED2022)
China International Conference on Electricity Distribution, 2022The transformation of urban cable feeders increases the number of mixed feeders in the distribution network, which make the randomness of the fault characteristics increases when a single-phase grounding fault occurs. The fault characteristics of the low

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 ...

Location Method of External Single-Phase Grounding Fault of Thermal Power Generating Unit
2022 4th International Conference on Power and Energy Technology (ICPET), 2022The external transmission line of large thermal power unit has complex structure, many overhead lines and branch lines, and the load distribution along the line is uneven. When a single-phase grounding short circuit occurs, it is impossible to accurately

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

Single-phase grounding fault identification and fault line selection for compensation grid
Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012A new grounding fault line selection method based on small-world network theory is proposed in order to solve the problems existing in grounding fault line selection device of compensation grid, such as that the correct rate of grounding fault line selection is not high and the selection device cannot recognize high-impedance and low-impedance ...
