- Core Type Transformer
In this type, the windings surround the core. The core is made up of laminated steel sheets stacked together to form a closed magnetic circuit. The primary and secondary windings are wound around the limbs of the core. This type of core is commonly used in distribution transformers due to its simplicity and ease of construction.
- Shell Type Transformer
In this type, the core surrounds the windings. The windings are placed inside the core, and the core is divided into two halves, resembling a shell. The primary and secondary windings are wound around a central limb within the core. Shell type transformers are typically used for higher voltage applications and have better short-circuit strength compared to core type transformers.
Both core types have their advantages and are used based on specific requirements such as voltage levels, power capacity, and space limitations. The choice between core type and shell type transformers depends on factors such as cost, efficiency, and application-specific considerations.
