How does a transformer booster connection function?

• A. Coils in series provide a 5% boost
• B. Coils in parallel provide a 10% boost
• C. Coils in series = 10% boost, Coils in parallel = 5% boost
• D. Coils in series do not influence boost

Answer: (C)

A transformer booster connection functions based on its configuration of coils, determining the voltage increase (or boost) in a system. When coils are connected in series, they combine their voltages, which can result in a higher voltage output. This is why a series connection is associated with a 10% boost. On the other hand, when coils are connected in parallel, the voltage remains the same as that of the individual coils, but the current capacity increases. However, in some systems, a parallel configuration can provide a boost due to how the transformer is engineered, resulting in a 5% boost. Thus, the specifics of the booster connection explain why both configurations impart different levels of boost—10% in series due to additive voltage and 5% in parallel influenced by the design and operational principles of the transformer. This understanding is crucial for linemen to ensure proper installation and operation of transformers in electrical distribution networks.
