What is a coil in transformer?
In a transformer, a coil is a cylindrical or coil-like structure usually made of insulating materials such as plastic or phenolic resin. It serves as a support structure for winding the coils of wire that form the primary and secondary windings of the transformer. The coil provides stability and protection to the windings, ensuring that they remain securely in place and properly insulated from each other and the transformer core.
Why do coils of transformers function?
A coil in a transformer refers to a continuous length of filter wound around a magnetic core. Coils are the fundamental components of transformers and are responsible for inducing electromagnetic voltage or current changes between primary and secondary circuits. In a transformer, there are two main coils: the primary coil and the secondary coil. The primary coil receives electrical energy from the input source, while the secondary coil delivers the output energy transformed into a charge. These coils are wound around the coil to form the primary and secondary windings of the transformer.
Why are two coils used in transformer?
Transformer winding techniques refer to the methods used to wind the coils around the transformer coil or core. There are several winding techniques, including concentric winding, sandwich winding, and helical winding. Each technique has its advantages and is chosen based on factors such as transformer design requirements, voltage rating and application needs. These techniques ensure that the coils are wound efficiently and effectively to achieve the desired electrical characteristics and transformer performance.
The two coils of a transformer are commonly called primary coil and secondary coil. The primary coil is connected to the input voltage source and the secondary coil is connected to the load. The primary coil induces a magnetic field in the transformer core when energized by the input voltage, which, in turn, induces a voltage in the secondary coil by electromagnetic induction. This voltage is then delivered to the load, allowing the transformer to transfer electrical energy from the primary circuit to the secondary circuit while maintaining the desired voltage transformation ratio.
