it says in neutral wire current flows under normal condition,
but when we put tester it wont glow, why?
Answer Posted / huzy
If you refer to the STAR connection of transformer winding, Its neutral point is connected to ground, Hence neutral is always at ground potential ( provided solid neutral earthing). Hence tester will not glow as it is at ground potential. Now the matter is current is flowing through the neutral is because of unbalance or fault in the system which will go to ground.

I am designing new project sub station with 220 kV / 11 kV, 40 MVA capacity. This project have many recifier sets, which can generate 3rd harmonics. Now I have to select vector group of This transformer. To minimise 3rd harmonics, what care should I take in selection of Transformer Vecrtor group? If it is Y-Y with open Delta tertiary then what should be the rating & voltage of Tertiary Winding?
