Why is it important for transformer coils to share no electrical connection?

The importance of transformer coils sharing no electrical connection primarily centers around the concepts of safety and isolation. When coils are electrically isolated, they prevent unwanted electrical current flow between different sections of the transformer. This isolation is crucial for protecting the transformer from faults and ensuring that each coil operates independently.

In such a configuration, safety is enhanced as it minimizes the risk of electric shock and short-circuit scenarios that could arise if there were an accidental connection between the coils. Moreover, isolation leads to greater reliability in the transformer’s operation since any potential failure in one coil does not directly impact the others, allowing the transformer to continue functioning effectively.

Furthermore, the isolation between coils contributes to efficient voltage transformation processes, enabling different voltage levels in the primary and secondary coils without interference. Thus, this designed isolation is a foundational principle in transformer functionality and safety.
