It is the number of turns of copper wire on one side of an iron transformer core to the number of turns on the opposite side of the same iron transformer core. eg. 100 turns on the primary to 25 turns on the secondary is the ratio of 4:1

What is difference betweena step up transformer and step down transformer?

The difference between the two transformers is the coil ratios between the primary and secondary windings. A transformer that increases voltage from primary to secondary has more secondary winding turns than primary winding turns and is called a step-up transformer. Conversely, a transformer with fewer secondary windings does just the opposite and is called a step-down transformer.

What is the Mathematical relationship between electrical power and the number of coils of wire?

There is none. There is a relationship between voltage and current and turns ratios in a transformer. But this rule remains - power in = power out. You don't get anything for free.

Why tap changer is required?

Tap changers are used to change transformer winding ratios by a specified amount (+/- 10%, for example). This allows more voltage control of one side with respect to the other. For a distribution transformer, as load increases, the voltage will sag. If it sags too far, a tap changer will be required to raise the voltage to acceptable values.

Can you use ordinary transformer in place of auto transformer?

yes we can place auto transformer in place of original transformer

What is a transformer that increases voltage?

A transformer that increases voltage is a step-up transformer.

What are taps for in a transformer?

The ratio of windings between a primary and secondary in a transformer govern the output voltage. Multiple taps are connections to various points in the coil effectively changing the winding ratios to get multiple voltages from the same transformer. Taps can be on the primary, secondary or both to provide a more versatile transformer.

How does the voltage varies through tap chinging of a transformer?

Voltage varies through tap changing of a transformer because the different taps connect to different points on the winding, with the result that use of different taps constitutes use of different turns ratios.

What are equivlent ratios?

when a number of ratios give the same answer after solving the ratios the ratios are said to be equivalent ratios

What is a tap changing transformer?

A transformer that has part of one winding partitioned in such a way that it can be removed or added to the winding. For example, you may have a transformer with 100 turns on the low side and 1000 turns on the high side. If it were a tap changing transformer on the high side winding, you may be able to add or subtract 100 turns, so the turns ratio can be anywhere from 9/1 to 10/1. <<>> This type of transformer is in common use in home distribution systems. On the side of the transformer there is a handle with the markings of 14,400/7200. By having this ability to work on two different primary voltages the utility only has to stock one transformer. The same transformer can be connected to the grid across phases at 14,400 or phase leg to ground at 7200 volts. The transformer ratios are so wound that the output voltage remains at 120/240.

How are ratios classified?

Ratios are often classified using the following terms: profitability ratios (also known as operating ratios), liquidity ratios, and solvency ratios.
