Now that I’m almost up the ladder,I should, no doubt, be feeling gladder,It is quite fine, the view and such,If just it didn’t shake so much.
In general, distribution transformers are used to reduce primary system voltages (2.4–34.5 kV) to utilization voltages (120–600 V). Table 3.1 gives standard transformer capacity and voltage ratings according to ANSI Standard C57.12.20-1964 for single-phase distribution transformers. Other voltages are also available, for example, 2400 × 7200, which is used on a 2400 V system that is to be changed later to 7200 V.
