WebUnlike an isolation transformer, variable autotransformers use a single winding and offers no interference or disturbance. Any given size autotransformer will support a load equal to its rated value whether it is connected in the 125 Volts to 250 Volts configuration, or in the 250 Volts to 125 Volts configuration. WebFor an autotransformer to work Properly the two windings must have the same sense of winding Operation It has a single coil wound on the core, but has four terminals, two for each circuit, and therefore has points in common with the transformer It consists of a winding of ends A and D, which has been made a derivation in the intermediate point B.

WebIf it went the other way, we'd be violating the law of conservation of energy. How the currents split between the halves of the autotransformer will then be determined by the windings ratio of the autotransformer, and the impedance of the load. Here's another direction to approach it. For an ideal (auto)transformer, P i n = P o u t.

In the example above, you would multiply 150 by 50 to get 7,500 and then divide that number by 1,000 to get 7.5 kilowatts. The last step is to convert the figure in kilowatts to kilovolt-amperes. When you do that, you’ll need to divide by 0.8, which represents the typical power factor of a load.
