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 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.

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

A method is described which has been used to reduce the difficulties encountered on several old delta-ungrounded systems. Data are included which will help in applying this to any particular power system. The scheme gives an alarm whenever a ground fault occurs, permits everything to keep running even more assuredly than with an ungrounded system, and ...
