Tips: Dyn11 Wiring Method of 3 Phase Step up & Step down Isolation Transformer
Dyn11 is ATO step up/down isolation transformers wiring method. D represents that the primary winding adopts triangular form wiring, Y represents the secondary measuring winding adopts star form wiring, n represents to lead the neutral line, 11 represents that the secondary winding phase angle lags 330 degrees compared with the first winding. If use clock representation method and assume the primary winding locates at the center of 12 o'clock, then the secondary winding locates at 11 o'clock position with an included angle of 30 degrees.
