Hi, some times when you charge the transformer after some
duration, trafo will take high inrush current. Due to that
it will trip on overcurrent but some times it can be also
give the triping on differential protection with
overcurrent.
So keep the setting slight high and then charge the
transformer. N after charging keep the setting as it is.
It might solve your problem but before that do the all test
on your trafo and then if nothing will found follow this.

Jiten
