Transformers used in Mines (With Diagram)
Transformers are used extensively at mines, both on the surface and underground. In order to keep voltage drop to a low value without using large cables, the electrical power is distributed at 3,300 volts or 6,600 volts. This voltage, while ideal for distribution, is too high for use on coalface machines or the smaller machines elsewhere ...
