ESSENTIAL DATA ON DESIGN AND USES

What is a Transformer?What is a Transformer? is a simple question to answer, though transformers will come in such a variety one might easily not recognize one on sight.

Transformers are static devices made up of one or more windings, in which those with two or more windings are coupled, and may be manufactured with or without a magnetic core.  They are used in induction of currents,  producing a coupling between two circuits.  Transformers typically change values of voltage and current and are always used in transferring power through electromagnetic induction between circuits at the same frequency. To the left are links to pages o this site that are about various kinds of transformers. One variation is the Auto Transformer.

A Transformer's output (neglecting losses due to resistance or other manufacturing and physical factors)  will be predictably computed by the general formula:
V
2/V
1=N2/N1

The proportion between N1 and N2 determines the exact final output (V2) as V1 will have to follow the same proportion with V2 as a result.

Simply put, where V equals voltage and N equals number of windings, and V1 and N1 are different than V2 and N2 respectively, we have the formula for establishing the exact specification for winding a Transformer, or determining the transformer you will need to purchase, based on the power you have and the need your equipment or service is designed for.

Example:
You have an incoming voltage (V
1) that is 120v. The primary windings (N1) are, say, 200. You add secondary windings (N2) of 400. N2 over N1 equals 400 over 200, or 2.  Therefore, V2, being proportionally increased, would have a simple relationship of V2 to V1 of two to one. The result would be a V2 of 240v.

Another calculation underlies the basis for why I (amperage, or current) drops as voltage rises.  The formula for this is:
P
(incoming) = I1V1 = P (outgoing) = I2V2

Since incoming power and outgoing power will always be the same, P does not change.  What this does in effect is to force amperage proportionately lower as voltage increases and the visa-versa.  One can therefore say that this lowered flow would result in a lowered resistance, even though the power, itself, has not changed.

Example:
P
(incoming) is 240w.  I1 is 2 amps and V2 is 120v.  If you change the voltage to the figure arrived at in the first computation above, 240v, then P is still 240w and I2 becomes 1 amp instead of 2 amps.  The resulting formula is as follows:
V
2/V1 = N2/N1 = I1/I2

The question What is a Transformer? introduces one to a plethora of applications.  They are used to alter or modify electrical flows under a wide variety of circumstances including low to high voltages, high to low voltages, too high or too low local voltages, protective systems for electronics and medical equipment, filters for adverse line phenomena, low voltage applications and others.

Large  Step-Up and Step-Down Transformers  are often specially constructed to stabilize or reduce temperature incurred when resistance in the lines creates heat.  They may be passively cooled through special oil baths, sometimes also having radiating vanes to dissipate heat, or through non-liquid coatings and heat dissipation vanes.  Some applications demand more cooling and will incorporate the use of fans or cooling baths of special gases.
