Power Transmission

A transformer is an electrical device by which the electromotive force of a source of alternating current

may be increased or decreased. They are widespread in long-distance power transmission as well as in

telephones, radio transmitters and receivers, television etc.

Nearly all transformers come under one of the two following classes: step up, and step down transformers.

In the transmission of electrical energy over wires for a long distance, transformers are practically

indispensable.

At the powerhouse in the distant mountains, for example, huge alternating current generators at the

relatively low voltage of several thousand volts generate electric current

If an attempt were made to transmit this electrical energy, at a voltage of say 2,200 volts, over many miles

of wire cable to a distant city, the current would be so large that nearly all of the energy would be

consumed in heating the power line. The heat generated (it should be remembered) is proportional to the

square of the current.

To avoid large heal losses, transformers at the powerhouse step the voltage up to some 220,000 volts before switching the current onto the power line. Since the voltage in the case cited is increased one hundred fold, the current drops by the same proportions to one-hundredth. Since the square of 1/100 is 1/10.000, the heat loss along the transmission line is only one ten thousandth of what it would have been had the transformer not been used.

At the city end of the power line, a transformer substation steps the voltage down to something like its original value of 2,200 volts. From there branch lines distribute the power to various sections of the city where smaller transformers, one near each group of several houses, step it down again to the relatively safe ioltageof 110to220 volts.
