If a distribution transformer with a ratio of 13 800 to 480 V is connected to the 13 800 V distribution feeder, range A of table 3-1 requires that the nominal 480 V secondary service be maintained by the supplying utility between a maximum of 126 V and a minimum of 114 V on the 120 V base. Since the base multiplier for the 480 V system is 480/120 or 4, the actual values are 4 á 126 or 504 V ...

Fluorescent and other discharge lighting can be used at 277 volts. 480 volt single phase, 480V three phase, and 277 volt single phase loads can be used on this system. Also good for minimizing voltage drops on long runs. Disadvantages are that a step down transformer is required to get 120/208 or 120/240 volt power for lights and outlets. Motors should be started directly from the generator ...

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 to 600 V for the remaining equipment until it ...
