Fault locating in ungrounded and high-resistance grounded systems
IEEE Transactions on Industry Applications, 2001One of the most common and difficult problems to solve in industrial power systems is the location and elimination of the ground fault. Ground faults that occur in ungrounded and high-resistance grounded systems do not draw enough current to trigger circuit breaker or fuse operation, making them difficult to localize. Techniques currently used to track

Resistance to adipocyte hyperplasia in ground squirrels given high-fat diets
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1987Mammalian hibernators prepare for the winter by depositing fat in existing fat cells. There is little, if any, production of new fat cells. This is curious because equivalent fat deposition in rats is associated with substantial fat cell production.

TENCON 2010 - 2010 IEEE Region 10 Conference, 2010
Power system is generally protected from lightning strokes by surge arresters which are provided with a low earth resistance connection to enable the large currents encountered to be effectively discharged to the general mass of earth. This offers some resistance to the flow of current which depends on electrode arrangements as well as the surrounding ...

International Journal of Emerging Electric Power Systems, 2011
Grounding arrangement is very important to maintain safe and reliable operation of a power system and to ensure safety of the power apparatus and operating personnel. In Saudi Arabia, the weather is dry and the soil resistivity varies significantly from area to area because the geodetic terrain varies from sea shore to the arid desert and dry mountains.

High-Resistance Grounding in the Cement Industry-A User's Experience
IEEE Transactions on Industry Applications, 1986The use of properly applied high-resistance grounding, with a method of tracing and locating the first fault, offers many advantages to the electrical power system including suppression of transient overvoltages, continued operation on the first ground fault, fast tracing of the first ground fault, and minimizing flash hazard. These benefits along with

Phase-Ground Fault Current Analysis and Protection of a High-Resistance Grounded Power System
2019 IEEE Industry Applications Society Annual Meeting, 2019This article provides a closer look at a high resistance grounded (HRG) power system using symmetrical components. It addresses the industry confusion, “how system charging current direction reverses during phase-ground fault condition without reversal of system voltage that causes fault current flow.” It presents fault current phasor diagram that ...

2006 China International Conference on Electricity Distribution (CICED 2006), 2006
This paper introduces the successful application of electrolytic pole in the inclined shafts to reduce the grounding resistance of the original ground grid in order to meet the designed requirements in the reconstruction of an existing substation in high soil resistivity area via the electrolyte generated from the electrolytic pole.
