Identifying ground fault location in High Resistance Grounded systems using Adjustable Speed Drive
2011 IEEE Energy Conversion Congress and Exposition, 2011One of the more difficult problems to solve in industrial plant is to locate and eliminate a ground fault in High Resistance Ground (HRG) system. This is because a ground fault conditions in these systems do not draw enough current to reliably trigger fault current sensors in the drive.

High-Resistance Grounding and Selective Ground Fault Protection for a Major Industrial Facility
IEEE Transactions on Industry Applications, 1984The high-resistance grounded system offers the distinct advantage of service continuity under single ground fault conditions which is critical to many industries such as petroleum, chemical, mining, textile, cement, pulp and paper, food, glass, utility, etc.

High-resistance grounding fault detection and location in DC railway system
11th IET International Conference on Developments in Power Systems Protection (DPSP 2012), 2012Locating high-resistance grounding faults poses a tough and challenging problem for the safety of DC railway systems. High-resistance grounding fault current isn't sufficient to trigger switches, which may expand the accident or turn into potential hazards.

A method is described which has been used to reduce the difficulties encountered on several old delta-ungrounded systems. Data are included which will help in applying this to any particular power system. The scheme gives an alarm whenever a ground fault occurs, permits everything to keep running even more assuredly than with an ungrounded system, and ...

A random matrix based high-resistance grounding fault detection method using PMU measurements
2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2016Ground fault through transition resistance is common in power systems highly impacting the correct action of protection. To improve the reliability of power systems, a random matrix based method is used in this paper as a backup protection to detect the high-resistance grounding fault, on the basis of successive PMU voltage measurements.

High-resistance grounding (HRG) is preferred in many industrial applications where continual operation during ground fault conditions is critical. However, there are some drawbacks for the traditional HRG detection methods to locate a ground fault in adjustable speed drive systems. The existing methods cannot detect or identify which phase faulted once

High-resistance grounding (HRG) is preferred in many industrial applications where the operation continuity is critical under ground fault conditions, such as pulp, paper, oil refining, chemical, glass, and metal industries. This is due to: 1) continuity of service; 2) minimized productivity impact with the scheduled system downtime; and 3) improved ...

A Phase Selection Element for High Resistance Ground Faults of Transmission Line
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019Zero sequence current differential protection can't select fault phase of transmission libe. Normal phase selection element is affected by load current and fault resistance, especially high resistance ground faults. A new phase selection method is proposed in this paper.
