AC MACHINES-1 (66761) Theory
Completion requirements
1. Understand working principle and construction of transformer.
1.7. Compare between the core type and shell type transformer.
In core type transformer both the primary and the secondary windings are placed on the side limbs whereas, in shell type transformer, the windings are placed on the central limbs of the transformer. The core type transformer has two magnetic circuits whereas the shell type transformer has one magnetic circuit.
Core type Transformer
In core type transformers, winding is positioned on two limbs of the core and there is ONLY one flux path and windings are circumventing the core.
Shell Type Transformer
In shell type transformers, winding is positioned on the middle limb of the core while other limbs are utilized as the mechanical support.
