High-resistance neutral grounding in industrial systems and the ground fault protection
2013 Brazilian Power Electronics Conference, 2013The objective of this paper is to present the state-of-the art in the high-resistance neutral grounding practice in LV (480V) and MV (4.16kV) industrial power systems, not still widely known in Brazil, especially regarding the ground fault detection and location systems, and equipment protection with selectivity.

Method to detect line-to-ground faults in high-resistance-ground networks
2010 IEEE Energy Conversion Congress and Exposition, 2010An Industrial-Power-Converter-System (IPCS) is a system made up of several power converters, such as Adjustable Speed Drive (ASDs), filters, and any kind of reactive power-compensation components. Today, an IPCS requires the ability to accurately detect and isolate electric faults to avoid further compromise of the integrity of the whole system.

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.

Selective high resistance grounding system for a cogeneration facility
2016 IEEE Pulp, Paper & Forest Industries Conference (PPFIC), 2015The paper describes a selective high resistance grounding (HRG) system for large industrial facility with two in-plant generators in cogeneration mode and two utility transformers. In a 5-step coordination using sensitive ground fault non-directional and directional relays, ground fault throughout the distribution system are cleared with a maximum ...

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.

1978 The Reality of High-Resistance Grounding
IEEE Transactions on Industry Applications, 1984In recognition of the successful applications of high-resistance grounding of industrial power systems primarily in the continuous process industries, an attempt is made to identify the broad application areas as well as to offer qualifications regarding the application of the high-resistance grounding concept.

High-Resistance Ground Retrofits in Pulp and Paper Mills
IEEE Industry Applications Magazine, 2001The safety and reliability of low-voltage, high-resistance grounding (HRG) schemes have made them an excellent choice for applications in the pulp, paper and other process industries. As facilities shift toward this technology for reliability in low-voltage substations, retrofitting existing grounded systems becomes the focus of several critical ...

II — Experience on a system with high ground resistance
Electrical Engineering, 1932FOR YEARS, lightning storms in the territory served by the Edison Electric Illuminating Company of Boston have been accompanied by numerous blown fuses, damaged and burned out transformers, and other troubles, all of which caused many outages to customers with consequent annoyance to them as well as expense to the company.

Digital fault location for high resistance grounded transmission lines
IEEE Transactions on Power Delivery, 1999This paper demonstrates that the presence of multiple load taps cannot be neglected for single-phase-to-ground fault location. A new method has been developed taking this into consideration, that can be applied to correct the location error due to intermediate power sources.
