Transformer tripping

Installed a system 2 years ago, which includes a vista mt-300 transformer.
There is a circuit breaker on each tap but also a primary circuit breaker. The primary breaker has been tripping. It was reset and tripped again about a day later.
This is all info i am getting relayed to me before i go onsite which is about an hour and half each way, so id like to figure a plan of action beforehand.
First, anyone have info for a specific problem?
Second, any tips or tricks with this? Its been working 2 years...
First thought is disconnect one of the 3 zones, reset breaker and see if it trips, repeat process until i find the faulty zone then try to figure out from there. Problem is that its so far to go back day after day after im hoping someone will have related experience that will shorten my process.....
