The proper implementation of high-resistance grounding of mine power systems reduces personnel hazards by limiting ground fault current and permits selective detection and clearing of faults. As described in IEEE Std. 142, high-resistance grounding employs a neutral resistor of high ohmic value, with the value of the resistor selected to limit the neutral ground resistor current to a magnitude equal to, or slightly greater than, the total capacitance charging current. Research has shown that… CONTINUE READING
