“…This is due to: (1) Continuity of service; (2) Minimized productivity impact with the scheduled system downtime; and (3) Improved safety concerns: elimination of arc flash hazards with phase to ground faults, suppression of transient line to ground over-voltages, and equipment damage reduction at the point of ground fault [1][2][3][4].…”

“…However, most of HRG GFI methods and papers focus on system level detection, such as generators, substations, power distribution panels, and so on [1][2][3][4][6][7][8]. Different methods must be combined in order to find the location of the fault.…”

“…As a result, National Electric Code (NEC) mandates the use of ground fault indicators when a ground fault occurs. References [1][2][3][4][6][7][8] discuss various Ground Fault Identification (GFI) methods in HRG systems.…”

In industrial plants with High Resistance Grounding (HRG) configuration, one of the most difficult problems is to accurately detect and locate a ground fault in Adjustable Speed Drive (ASD) systems. This is because: (1) HRG ground fault current (1-10A) cannot reliably trip the over current protection function in drives; (2) In modern industrial plants, the existing methods are hard to detect and locate low voltage/low frequency ground faults; (3) With the existing methods, the fault location will be manually checked one by one using an ammeter. This paper will present a HRG ground fault self-diagnosis method for multi-ASD systems. The proposed method can solve the issues mentioned above: (1) Reliable HRG ground fault detection with wide motor speed range; (2) The HRG ground fault can be easily identified in multi-ASD systems; (3) The identification process is performed by the proposed self-diagnosis method, no trained technician is required during the identification process.

“…In order to identify the faulty line with a SGF in distribution systems, many principles and methods have been proposed in the past [2][3][4][5][6][7][8], such as the opening line approach [2], the injection signal technique [3] and the method based on steady components of fault currents [4]. The traditional methods have various shortcomings including long outage time, inaccuracy and possible misoperation.…”
