It was also mentioned that this 208 voltage should not be confused with the 208 V coming from the secondary of the Wye service transformer. Figure 1 shows a center-tapped Delta transformer. It also ...

The electrical configuration of the delta-wye transformer makes it the most popular transformer connection in the world. When it comes to making proper transformer connections, more industry ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

For the remainder of this article, the term “Wye” will be used to describe this transformer’s secondary windings. (My March 3, 2003 column dealt with the secondary windings of a Delta service ...

Three phase power transformer secondaries that are set up in a delta configuration do not have an earthing or grounding point. By contrast, a wye configuration of windings would provide such a point, ...

On an 11 kV system, the 100 kVA delta-wye transformer would have a load current of about 5.3 amperes and a primary current for a secondary fault on the order of 0.05 amperes. Therefore, the primary ...

The facility has its own 1,000-kVA delta-wye transformer that steps-down the 25 kV to 30/400 V for the panelboards distributed through the plant. The low-voltage side of the installation is ...
