Description : State the different types of transformers. Describe the construction and general principle of transformer.
Answer : Different types of transformer are core type shell type Berry type Construction of transformer: OR Shell Type construction can be consider for diagram Transformer ... is based on the principle of mutual induction between two circuits linked by a common magnetic field.
Description : Compare core type transformer and shell type transformer on the following parameters. (i) Types of winding used, (ii) Application
Answer : Ans:
Description : Protection of transformer from all types of faults is by using (A) over current relay (B) differential relay (C) distance relay (D) Buchholz relay
Answer : Transformer noise is generated due to vibration of core and winding this is because of magnetostriction and magnetomotive force.
