Answer Posted / earnest paul
It means that the LV winding voltage lags the HV winding
voltage by 30 degrees.
The 11 typically means 11 o'clock on a standard clock.
whenever you see a vector group like Dy11 ar Yd1 or Yd5 ...
all you have to do is first FIX THE HV WINDING AT 12 o clock
now the 11 shows that it is behind 12 on the clock so you
can say that the LV is lagging by....30 degrees
in Yd1, the lv windings is at 1 o' clock meaning it is
ahead of 12 o clock by thirty degrees so it means that the
LV winding leads the HV winding voltage by 30 degrees
in Yd5, the lv windings is at 5 o' clock meaning it is
ahead of 12 o clock by 150 degrees so it means that the LV
winding leads the HV winding voltage by 150 degrees
