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 ...

Transient processes at single phase-to-ground faults in combined grounded networks
2012 Electric Power Quality and Supply Reliability, 2012This paper deals with the combined method of neutral grounding when a high-value resistor is continuously connected to a neutral in parallel with a Petersen coil. Monitoring of processes at single phase-to-ground faults was organized in the 6 kV network of the large-scale iron and steel plant.

2020 5th International Conference on Power and Renewable Energy (ICPRE), 2020
The fault characteristics of the small current grounding system are not obvious when the fault occurs. Currently, it is hard to accurately select and locate the ground fault in the small current grounding system. Therefore, in this paper, a scheme of fault grounding line selection and location is proposed based on the characteristic of the zero ...
