Large three-phase power transformers are generally referred to as what?

• A. Banks
• B. Modules
• C. Units
• D. Assemblies

Answer: (A)

In power distribution practice, a large three-phase transformer is typically described as a bank of transformers. This term reflects how such installations are usually built from multiple individual transformer units mounted together to handle the high three-phase rating. The bank concept emphasizes that the units operate as a single, coordinated set, often with the windings connected in delta or wye to provide the required three-phase power. The other terms are less fitting because they don’t convey the idea of a grouped, multi-unit assembly that forms the complete three-phase transformer.
