13.8 kV selective high-resistance grounding system for a geothermal generating plant — A case study


13.8 kV selective high resistance grounding systems for bus connected generators are non-existent due to two reasons: One, the stray capacitance current of the system can be high, (>;10-12A); second the sensitivity and selectivity of the ground fault devices to detect low-levels of ground fault currents is required. The paper describes the relay types… (More)
