Delta–Wye Transformer – 4 wire – HRG system – unbalanced load and ground fault

Last Update: November 1, 2024

Duration: 21 minutes
Creation Date: October 22, 2024

Topics:
– Secondary line to line voltages not impacted by ground fault or unbalanced load
– Secondary line to neutural voltages not impacted by ground fault or unbalanced load
– Secondary line to ground voltages impacted by ground fault and not by unbalanced load
– Neutural to Ground voltages with ground fault
– Common Mode currents in connections to ground impacted by ground fault, not by unbalanced load
– Line currents into the wye load not impacted by ground fault and impacted by unbalanced loads
– Line current on faulted phase of secondary moderately higher than other phases - no fault protection tripping
– Unbalanced loads results in current in the neutral conductor
– Ground Fault Current limited by HRG
