Three-winding transformer and charging current on resistance grounded secondary
Hi, I need to add a NGR (neutral grounding resistor) to a Customer specified three-winding transformer with following parameters: Primary: 46kV, wye-connected with solidly grounded neutral. 46kV system is solidly grounded. Secondary: 4.16kV, wye-connected. To add NGR on this winding. Buried...- pejap
