Directional ground fault indicator for high-resistance grounded systems
IEEE Technical Conference Industrial and Commerical Power Systems, 2002Locating ground faults is a difficult and challenging problem for low-voltage power systems that are ungrounded or have high-impedance grounding. Recent work in pilot signals has renewed efforts in developing fault location methodologies. This paper presents a method for directional ground-fault indication that utilizes the fundamental frequency ...

High Resistance Grounding—Avoiding Unnecessary Pitfalls
IEEE Transactions on Industry Applications, 2007The high resistance grounding (HRG) of 480-4160-V industrial power systems increases service continuity, enhances personnel safety, and reduces equipment damage when a ground fault occurs. HRG allows maintenance personnel to quickly and safely locate a ground fault while avoiding unscheduled downtime.

Advanced concepts in high resistance grounding
2012 Petroleum and Chemical Industry Conference (PCIC), 2012Resistance grounding is relatively simple and easy to apply in radial distribution systems at Low Voltage. When high resistance grounding is applied, using one Neutral Grounding Resistor at the supply transformer, an alarm system to detect and indicate the ground fault is then required by the installation codes.

High Resistance Neutral Grounding [History]
IEEE Industry Applications Magazine, 2012The last two decades of the 19th century witnessed a rising interest in electrical power projects and a heated debate about using direct current (dc) or alternating current (ac) systems as the backbone of generating and transmitting power. The debate escalated and it was dubbed the "War of Currents." By 19th century measurements, the Niagara Falls ...

Decreasing the ground resistance of a grounding system in high resistivity soil is often a formidable task. A new method is proposed to decrease ground resistances. This method requires three steps: (1) drilling deep holes in the ground; (2) developing cracks in the soil by means of explosions in the holes; and (3) filling the holes with low ...

Measurements of grounding resistances for high impulse currents
IEE Proceedings - Generation, Transmission and Distribution, 1998The paper presents field measurements of surge characteristics of a concrete pole, a buried single conductor and a grounding net for high-impulse currents with a maximum magnitude of 40 kA and with a wavefront duration of a few microseconds. The measured results show that the grounding resistances are greatly dependent on the applied currents and have ...

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.

High-resistance grounding of electrical power systems offers many of the advantages of both solidly grounded systems and ungrounded systems, including practical suppression of transient overvoltages, practical reduction of equipment damage due to ground fault, and the ability to continue to operate a system with a ground fault present on one phase. The
