Answer Posted / amit biswas
DYn11 means a step up tr. where pr. side is delta connected
and sec side is star connected."n" stands for neutral which
means a netral is taken from the star point of the sec. wdg.
11 means sec is leading the the pr. by 30 deg.
using neutral is essential for zero seq. protection
