WebFor example, when testing a CT on the H1 to H3 primary delta winding, you would short the H3 and H2 bushings together. Separate from this, you would also short all secondary terminals (e.g., X1, X2, X3, and X0 if it is a WYE winding). Finally, you would short the tertiary terminals if the transformer has tertiary windings. Web21 May 2013 · Two possible connections—Delta & Wye The Wye connection joins together one end of each of the coils and applies the individual phases to the open ends. These two connections produce very different results when power is applied. An advantage of the Delta connection is higher reliability.

Web17 Dec 2014 · Location. Norfolk - UK. Dec 17, 2014. #20. One of the advantages of a tertiary winding is that you can pass dc through it if the transformer is gapped. This eliminates a blocking capacitor in the NFB loop and hence removes a pole and a zero from the transfer function, thus aiding stability. Cheers. Ian.
