Answer Posted / omar aziz
Every power transformer has a vector group listed by its
manufacturer. Fundamentally it tells you the information
about how the windings are connected (delta or wye) and the
phace difference betweent the current and voltage. EG.
DYN11 means Delta primary, Wye Secondry and the current is
at 11 o clock reffered to the voltage.
