Transformer Core Are Laminated For What Purpose

Purpose of transformer core.

Transformer core are laminated for what purpose.

The eddy currents cause energy to be lost from the transformer as they heat up the core meaning that electrical energy is being wasted as unwanted heat energy. A transformer core is laminated to a reduce hysteresis loss b reduce eddy current losses c reduce copper losses d reduce all above losses. The main purpose of a transformer core is to provide a closed magnetic path to the magnetic flux. In an electrical power transformer there are primary secondary and sometimes also tertiary windings.

These are the core type and shell type. The core is laminated to reduce these to a minimum as they interfere with the efficient transfer of energy from the primary coil to the secondary one. Electrical energy can be transferred between separate coils without a metallic conductive connection between the two circuits. The performance of a transformer mainly depends upon the flux linkages between these windings.

A varying current in any one coil of the transformer produces a varying magnetic flux in the transformer s core which induces a varying electromotive force across any other coils wound around the same core. Without disturbing the closeness of the magnetic path we can design two types of core.
