what is High resistance grounding and whatis the criteria
for the selection of High resistance grounding
Answer / akshay chauhan
High Resistance Grounding (HRG) is a method where high resistance is connected between a system's neutral point and ground to limit ground fault current, usually to less than 10 amps, allowing the system to continue operating during a single ground fault while protecting equipment.
Selection Criteria:
System Voltage: Suitable for low (up to 600V) and medium-voltage (up to 15kV) systems.
Fault Current Limit: Typically limits fault current to 5-10 amps.
Neutral Availability: Requires an accessible neutral point (e.g., wye transformer).
System Continuity: Used where continuous operation during faults is critical.
Ground Fault Detection: Should include monitoring for fault identification.
