The Reality of High-Resistance Grounding
IEEE Transactions on Industry Applications, 1977In 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.

Practical evaluation of ground enhancing compounds for high soil resistivities
2010 30th International Conference on Lightning Protection (ICLP), 2010In order to study the long-term effect of using “ground enhancing compounds” in conjunction with various ground electrodes, a common project between Electrical Research Institute (IIE) and the Mexican Electrical Utility (CFE), was started in 2007. The aim of the project is to characterize the ground enhancing compounds in order to obtain the relative ...

Improved Electrical Safety Through High Resistance Grounding
IEEE Transactions on Industry Applications, 2015High resistance grounding (HRG) is a well-proven technology for improving electric reliability for many industrial and utility facilities such as used in petrochemical, automotive, and generating plants. Many such facilities require the increased reliability for production and operational reasons.

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.
