Charging Current Data for Guesswork-Free Design of High-Resistance Grounded Systems

The design of high-resistance grounded power systems requires the sizing of the grounding resistor to provide a current flow equal to or greater than three times the system charging current (Ico) of each phase. In industrial power systems the insulated power cables are a major source of system charging current which flows into line-to-ground faults. Data… (More)
