After the source was converted to 480 V, the same buck-boost transformer could be turned around and used to convert 480 V to 600 V for the remaining equipment until it could be converted to the 480 V level. At the conclusion of the conversion, the standard 480 to 120 V transformer …

The most common type of control transformer has two primary coils and one secondary coil, as shown in Figure 1.9. Figure 1.9: A Typical Control Transformer Configuration. In most cases, the control transformer is used to reduce the main or line voltage of 240 VAC or 480 VAC to a control voltage of 120 VAC. Notice that the primary windings are ...
