What does Transformer vector connection Dy11y5 means?
Answer Posted / nitin khatana
D stand for hv winding in delta and y stand for lv winding in star.
11 stand for 30 degree lead.
and Dy5 means D stand for hv winding in delta and y stand for lv winding in star.
5 stands for 150 degree lag.
The Dy5 is not a legal 3 phase connection. it is obtain from Dy1 connection by change the connection of lv star winding star(form star from a1b1c1 to a2b2c2 to form Dy5 connection)

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
