Hello All,
1.Star connected earthed neutral Source to Star connected earthed neutral load? Say if a L-G fault occurs between the source and load, How does the fault current gets distributed? To the source side neutral or load side neutral?
2.Star- Star Transformer. Neutral earthed on both the primary and secondary. say If a L-G fault occurs on secondary side, does the fault current flow in to the primary side neutral too? How does the fault current reflected in the primary?
3. Star- Delta Transformer. Neutral earthed on Star side. say If a L-G fault occurs on Delta side, does the fault current flow in to the star side neutral? How does the fault current reflected in the star side.
Thanks beforehand.
