Health is wealthTransformer Core
The cores used in the transformer are generally made up of laminated silicon steel with high permeability (to minimize eddy current losses). The cores are rectangular in shape due to many reasons as stated below:
1. Their winding requires lesser complexity and hence equipment is cheaper.
2. They are robust and need very less maintenance.
3. There is very small inflow of current when switched on
4. Central fixing is easy.
Current Transformers and Potential Transformers have ring-type cores. Power transformers have cubical cores. The ideal transformer is to have all the magnetic flux produced by one winding linking the other. Flux that does not link both windings is called Leakage. It is affected by the shape of the core and by arrangement of the windings. To reduce leakage, the core must be compact and windings close together.
