A Decentralized Fault Detection Technique for Detecting Single Phase to Ground Faults in Power Distribution Systems With Resonant Grounding

IEEE Transactions on Power Delivery, 2018
This paper presents a decentralized fault detection technique for power distribution systems with resonant grounding. The aim of this paper is to detect single phase to ground faults and identify the faulty feeder within three cycles of the fault occurrence. In the proposed technique, faults are first detected based on the neutral voltage displacement.

Detection of Single-Phase to Ground Faults in Low-Resistance Grounded MV Systems

IEEE Transactions on Power Delivery, 2021
The 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 ...

Identification of Feeder with Single-Phase Ground Fault

2019 International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2019
Single-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).

A fault location method for single-phase grounding fault in distribution network

The 27th Chinese Control and Decision Conference (2015 CCDC), 2015
The 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, 2012
This 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.
