Electrical Ac Machine (part)-1: Working Principles and Construction of Transformer


A static electrical device or circuit that transformer circuit electric power transfer from the other. Frequency of supply remains unchanged in the move, but the amount of change in voltage and electrical outlets.

Both primary and secondary coil are connected to each other transformers area magnetic. That one circuit to another by electro- magnetic Induction circuit energy transfer occurs. Energy transfer occurs only in one circuit to another  transformers circuits, but does not convert to energy.
Generally, each connected by two  magnetic flux transformers mutual   Induction of work. transformer are reluctance with a low burr of the common magnetic circuit are electrically inductance circuit are isolated from each other.
Implicate a common magnetic coil has two people circuit mutual  inductance too. Which is a common transformer . AC voltage to a coil associated with the two coils coil one the AC current to flow. The AC current magnetic circuit flux makes  which is connected to both, and both coil, coils electrical voltage generated by the magnetic field. The first coil (supply attached) voltage resistance and current flow and the secondary coil voltage of the voltage source to a load of work.
If the DC supply is also a transformer, the transformer primary and the secondary coil is connected to two magnetic field are inductive  resistance coil with very little. If the DC supply only or supply transformer switch on and off transients voltage to be generated. Voltage will be generated at any other time. If the DC supply voltage will not damage the primary coil.
transformer categorize all talk?
Structurally transformer four types, namely: -
1. Core type transformer.
2. Shell type transformer
3. Ribbon type transformer.
4. Spiral core transformer.
Primary and secondary coil to the relations of the two types of transformer -
1. Conventional transformer.
2. Auto transformer.
Primary and secondary voltage ratio of the two types of transformer -
1. Step up transformer.
2. step down transformer.
Supply system of the two types -
. Single phase transformer.
. Three phase transformer.
Services or performance of the three types of transformer -
1. Power transformer.
2. Distribution transformer.
3. Instrument transformer.
transformer three types of installation -
. Indoor type transformer.
. Outdoor type transformer.
. Pole mounted transformer.
Frequency of working transformer two types -
. Audio frequency transformer.
. Radio frequency transformer.
transformer two types of instrument -
1. Current transformer.
2. Potential transformer.
Also useful are several types of special transformer -
1. Constant current transformer.
2. High leakage transformer.
3. Welding transformer.
4. Polarized transformer.
5. Teaser transformer.
 Transformer is a variety of names: -
Transformer and other instruments, including the large size of the power distribution Transformer 
Transformer All the basic elements -
1. The core 2.Coil or winding 3. Insulation .
With large transformers with fittings -
1 The transformer tank. Busing 3. conservator 4. Breather 5. tape changer 6. Explosion bend7. Terminal box.

  1. Do you know how current gets transformed to your cities or state, it is through the help of transformers. Transformers are the storage device for electricity that transforms electric circuit from one to other and many industries depend upon the transformer for their industrial use. It was discovered by Michael Faraday and Joseph Henry in 1831 and the first credit goes to Faraday for his experiments. It has two windings and it is based on two principles such as, it can produce magnetic filed and the changing magnetic field can induce voltage across the ends of the coil.
