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.

How to Test Step Up & Step Down Isolation Transformer?

Need more detail of ATO isolation transformer? Here is a good explanation about it in this video. To test the accuracy of the transformer voltage, we take a 3000 VA single phase 220V iuput to 110V output isolation transformer as an example.

Existing reviews of 5 kVA Isolation Transformer, 3 phase, 480V to 400V

Is your isolation transformer bidirectional?

For example, if your transformer is to convert 3ph, 220V primary to 3ph, 400V secondary, and I apply 3ph, 400V at secondary side, will I get 3ph, 220V at primary side?
