A single-phase 10-kVA 480/120-V transformer is to be used as an autotransformer tying a 600-V distribution line to a 480-V load. When it is tested as a conventional transformer, the following values are measured on the primary (480-V) side of the transformer: Open-circuit test Short-circuit test

31-23. A step-up transformer has 400 secondary turns and only 100 primary turns. A 120-V alternating voltage is connected to the primary coil. What is the output voltage? Es = 480 V. 31-24. A step-down transformer is used to drop an alternating voltage from 10,000 to 500 V. What must be the ratio of secondary turns to primary turns?

Nowadays that thought has changed and we are using 400 V instead of 440 V, or 230 V instead of 220 V. ... 240 volt output— can have the output connected to a 240 volt source and thereby become the primary or input to the transformer, then the original 480 volt primary winding will become the output or 480 …

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 ...

The conversion to 480 V could be accomplished by the use of a standard 480 to 120 V transformer. The 480 V winding was connected in series with the 120 V winding, thus obtaining 600 V. The neutral was common to both systems. After the source was converted to 480 V, the same buck-boost transformer could be turned around and used to convert 480 V ...
