Finding fault - Locating a ground fault in low-voltage, high-resistance grounded systems via the single-processor concept for circuit protection

IEEE Industry Applications Magazine, 2007
High-resistance grounded systems have distinct advantages over solidly grounded systems in facilities where very reliable delivery of power to the loads is desirable. Unlike solidly grounded systems, resistance- grounded systems are able to operate continuously with one unintentional ground. However, this is true for only the first ground fault.

High-Resistance Grounded power system equivalent circuit damage at the line-ground fault location (Part 1)

2013 IEEE Industry Applications Society Annual Meeting, 2013
This paper provides an electrical equivalent circuit of a High-Resistance Grounded (HRG) power supply transformer to discuss damage at a fault location so long as the fault remains a line-ground fault. Fault resistance and fault current that have an effect on damage are included in the equivalent circuit. Three-line diagrams showing fault current flows
