Distinguish between core-type and shell-type transformer.
The main difference between Core type and Shell Type Transformer is the constructional difference of their coreand winding arrangement. In core type transformer, the magnetic coreconsists of two limbs and two yokes whereas in Shell type transformer, there are three limbs and two yokes.
Why is the low- 7M voltage winding placed near the core?
If we place high voltage winding nearto core then more insulation is required To insulate the coil from core. This is the one reason that it is economical to place low voltage winding near to core… Both windingsare placed are wrapped around thecore and isolated from each other.
Why is the core of a transformer laminated?
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. 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.
