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.
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.
Purpose of transformer core.
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.
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.
A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another or multiple circuits.
In an electrical power transformer there are primary secondary and sometimes also tertiary windings.
The main purpose of a transformer core is to provide a closed magnetic path to the magnetic flux.
Electrical energy can be transferred between separate coils without a metallic conductive connection between the two circuits.
Without disturbing the closeness of the magnetic path we can design two types of core.
These are the core type and shell type.
