High-Resistance Grounded Power Systems--Why Not?
IEEE Transactions on Industry Applications, 1976Many systems could be high-resistance grounded--with the traceable signal to locate the first ground fault--to result in a safe, economical, reliable, and uncomplicated method of grounding of 480-.

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.

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.

High-Resistance Grounded Power System
IEEE Transactions on Industry Applications, 2015To minimize ground fault during a line-to-ground fault condition, it has been a common practice to use high-resistance grounded (HRG) power systems, both at low voltage and at medium voltage (MV). The criteria for designing HRG systems are very well known to the industry; however, the opinion of industry experts has been divided on limiting the use of ...

Applying High-Resistance Neutral Grounding in Medium-Voltage Systems
IEEE Transactions on Industry Applications, 2010The application of high-resistance neutral grounding (HRNG) to medium-voltage (MV) distribution systems is one of the least understood and often misapplied methods of system neutral grounding. An HRNG grounded system is the only intentionally grounded neutral grounding method suitable for industrial systems that allows normal operation (no voltage dips,

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 ...

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 ...
