Hello,
I am seeking recommended protection settings for our new Tie-Line transformer. The transformer is an ABB Oil Immersed Transformer rated at 34.5kV high side - 13.2kV low side. Any help will be appreciated.
I'm fairly new at this so here goes: We have a Star connected gen. bus with a floating neutral for one of our power plants which is rated at 13.2k. It's grounded by a zig-zag transformer rated at 50A continuous current and 400A 10sec rating capacity. So I was task to figure out how to calculate...
