Improving Reliability of a 20 kV HRG Distribution Feeder Using Directional Ground and VROC Relays

A 20 kV distribution feeder with high-resistance grounding (HRG) at PLN ULP Sutojayan was investigated to address recurrent maloperation of conventional overcurrent and ground-fault protection under low ground-fault current conditions. The feeder neutral is grounded through a 500Ω resistor, which limits single line-to-...
