    Product Application Areas
     isolation transformer application fieldTips: DYn11 Wiring Method
    DYn11 is ATO 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.
