Construction and Working Principle of Transformers, Its
A transformer works by mutual induction between two windings linked by a magnetic core. It transfers electrical power from one circuit to another without changing frequency. Transformers can increase or decrease voltage with corresponding changes in current. Transformers are classified based on construction (core or shell type), cooling method (oil or air), number of …

5. BASIC PRINCIPLE Transformer comprises a closed magnetic circuit called core. Two or more windings are placed on the core as per design criteria. The operating frequency in our country is 50 C/S. Core provides a high permeability path to the magnetic circuit besides supporting the winding. When 50 C/S supply is given to a winding called primary …
Transformers
transformer rating is given in kVA. Temperature rise resulting from losses is a determining factor in the rating of machine. Pc – depends on current Pi – depends on Bm which depends on voltage Total losses depend on volt ampere product only not on phase angle between V & I. So transformer is rated in kVA. Why transformer rated in KVA ? s -tion
