High-resistance grounding (HRG) is preferred in many industrial applications where the operation continuity is critical under ground fault conditions, such as pulp, paper, oil refining, chemical, glass, and metal industries. This is due to: 1) continuity of service; 2) minimized productivity impact with the scheduled system downtime; and 3) improved ...

The Problem of Ground Faults on Overhead Lines with High Earth Return Resistance
2019 IEEE IAS Pulp, Paper and Forest Industries Conference (PPFIC), 2019The purpose of this paper is to consider the impact of high resistivity soil on ground current from fallen overhead lines via a hypothetical earth path resistance calculation. A second major thrust is consideration of solutions to the related problem of how to detect and automatically de-energize overhead lines when they fall. The relevance of specific

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.

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
