Hi,

working on my take home aqp. If a dc gen fails, I know the main busses will tie thanks to the bus tie logic system. What I want to make sure I'm clear on is, the secondary busses will not tie so long as the mains tie. If for some reason the mains fail to tie, perhaps due to both dc gens failing, that is when the secondaries will tie, providing current via the trus to each main?

Thanks
