Most Commonly used Transformer Construction

Statement: Which form of Transformer Construction is practically used the most

Correct answer: 1. Shell form

The shell structure construction uses a particular configuration in which one winding is wrapped around the another one. Since these settings provide a number of benefits over the core type, it is most commonly used in practical systems. Here the high winding is insulated from the core and the leakage flux decreases to a very small value. So this configuration is most commonly employed in practical transformers.
