Transformer Core Are Laminated For What Purpose

For efficient flux linking between these windings one low reluctance magnetic path common to all windings should be provided in the transformer.

Transformer core are laminated for what purpose.

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. In an electrical power transformer there are primary secondary and sometimes also tertiary windings. A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another or multiple circuits. Purpose of transformer core.

Electrical energy can be transferred between separate coils without a metallic conductive connection between the two circuits. These are the core type and shell type. The main purpose of a transformer core is to provide a closed magnetic path to the magnetic flux. 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 performance of a transformer mainly depends upon the flux linkages between these windings.
