Identification of Feeder with Single-Phase Ground Fault
2019 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2019Single-phase ground fault in overhead power lines is one of the most usual types of fault in power grids of 6-35 kV. The arc fault generate a spectrum of higher harmonics of voltage and current. This higher harmonics can be the indication of the fault mode. Illegible higher harmonics can be appearing after removing the main harmonic (50 Hz).

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

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 ...

A fault location method for single-phase grounding fault in distribution network
The 27th Chinese Control and Decision Conference (2015 CCDC), 2015The single-phase grounding fault is the most common fault among all types of faults in distribution network. It is of great importance to locate the single phase grounding fault accurately and quickly for reducing economic losses. Aiming at the location of single-phase grounding fault in distribution network, this paper puts forward a new fault ...
