The central type transformer is an everyday and vital electrical device that is used for the transformation of voltages within power systems. It plays an important role in the electrical transmission and distribution that helps increase and decrease the voltage quickly. These types of transformers are utilized in power plants substations, as well as in a variety of industrial processes.
The article explains the basics of what a transformer of this type is, its function and its design, uses as well as the advantages and disadvantages, and what it has to offer over different types of transformers. Additionally, we’ve included an FAQ section that addresses commonly asked questions.
What is a Core Type Transformer?
Core type transformers are Core type transformer is a kind of transformer that has the coils (coils) are wrapped around the branches of the magnetic core. The core is the conduit for the magnetic flux that is vital for the transfer of energies from the first coil onto the second and vice versa, without electrical connections between the two.
The core is composed from laminated silicon steel in order in order to minimize the energy lost caused by Eddy currents. The core can be either oval or rectangular and the wires are wound between the limbs and the core.
Construction of a Core Type Transformer
A transformer of the core type typically comprises:
-
Magnetic Core: Constructed from steel sheets laminated for reducing loss of eddy current.
-
Primarily Winding connected to power supply, produces magnetic flux.
-
Secondary winding The secondary winding delivers the changed voltage to the device.
-
Insulation It is used between windings and the core to prevent short circuits.
-
Cooling Systems may contain air or oil cooling to control temperature.
The windings usually are put on the opposite limbs the core, to allow for greater circulation of flux. The arrangement helps make the transformer much more efficient, and simpler to build both in large and medium sizes.
Working Principle
The basic type transformer operates by using the concept that electromagnetic induction works. This is a step-by-step guide to understanding the principle of electromagnetic induction:
-
The primary winding is hooked up via the AC electricity source.
-
The alternating current creates magnetic fields that change in the vicinity of the winding that is primary.
-
The magnetic field that flows through the center and joins with another winding.
-
In accordance with The Law of Faraday the changing magnetic flux creates Electromotive Force (EMF) within secondary windings.
-
The voltage of the second winding is dependent on the ratio of turns between two windings.
Types of Core Used
There are various types of shapes and arrangement of cores that are used in transformers. Most common shapes of cores used in transformers with cores include:
| Core Shape | Description | Usage |
|---|---|---|
| Rectangular Core | Simple design, simple to make | Small to medium-sized transformers |
| Square Core | Symmetrical, better flux distribution | Medium transformers |
| Cruciform Core | Lowers the area of core, more efficient | High-efficiency technologies |
| Step-lap Core | Limits the leakage of flux | High-voltage transformers |
