What is winding transformer?
A winding is the name given each of the coils wound around the transformer's core. A basic transformer has two windings, termed the primary winding (connected to the supply) and the secondary winding (connected to the load).
Why a two winding transformer is used instead of single winding transformer?
You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.
How could you convert step up transformer into step down transformer?
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
When a two winding transformer is connected as an autotransformer its efficiency under full load is?

How can you identify which one is step up or step down transformer?
A transformer has two windings, termed the 'primary winding' and the 'secondary winding'. The primary winding is the winding connected to the supply, while the secondary winding is connected to the load. The secondary voltage of a 'step up' transformer is higher than the primary voltage; the secondary voltage of a 'step down' transformer is lower than the primary voltage. The simplest way to determine whether a transformer is a step up or step down, is to measure the primary and secondary voltages. If you are simply looking at a transformer, then the transformer's insulated bushings will give you a clue -the higher voltage bushings are much bigger than the lower voltage bushings. If you have access to the inside of the transformer, then the higher voltage windings are thinner and have a greater number of turns than the lower-voltage winding.

Is it necessary to use three winding transformer or two winding one is enough when we have svc in the network?

Conversion of 2-winding transformer into auto transformer?
Yes, you can use a mutual (2-winding) transformer as an autotransformer, by connecting the two windings in series. For example, if you have a 240:120 V transformer, connecting the two windings in series and supplying the 240-V winding with 240 V can give you a secondary voltage of 360 V. But you must take into account the polarity of the transformer, and realise its capacity will change.

What is the difference between transformers and autotransformers?
A transformer or, more-properly, a mutual transformer, has two windings, the primary and the secondary, which are electrically-isolated from each other, with the secondary voltage induced through mutual induction. An autotransformerconsists of one tapped winding, so the secondary circuit is not electrically isolated from the primary circuit. An autotransformer may be used to either increase or decrease the primary voltage, depending how it is connected.
What is single phase autotransformer?
An autotransformer is a transformer with at least two windings where a part of one winding (the common winding) is shared between both primary and secondary outputs.
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 set up for a transformer that decreases the voltage on the out put side?
A basic, two-winding, transformer consists of two, separate, coils (called windings) wound around a laminated silicon-steel core. The winding connected to the supply (input) is called the primary winding, and the winding supplying the load is called the secondary winding. Alternating current flowing in the primary winding sets up an alternating magnetic field in the core which induces a voltage into the secondary winding. If there are fewer turns in the secondary winding, then the secondary voltage is lower than the primary voltage. If there are more turns in the secondary winding, then the secondary voltage is higher than the primary voltage.
Why do you use Two Winding run and start winding in the single phase motor?
Any transformer uses a minimum of two windings to change the voltage value. The primary side of the transformer is usually connected to the existing voltage. The secondary side of the transformer is usually connected to the load, who's voltage could be higher or lower voltage than the primary voltage.If the secondary voltage is increased the transformer is known as a step up transformer and if the secondary voltage is decreased the transformer is known as a step down transformer.The transformer terminal markings for the primary are H1 and H2 on a single coil primary and H1 to H4 on a dual voltage primary winding. Like wise the secondary terminal markings are X1 and X2 on a single coil secondary and X1 to X4 on a dual voltage secondary winding.
