What features characterize an ABB oil filled transformer?

ABB oil filled transformers are typically characterized by strong compliance with utility standards, robust thermal design, and configurable monitoring and protection options. Common features include high quality bushings, tap changer options with monitoring, sealed or conservator designs, temperature and oil level instrumentation, and compatibility with online sensors such as moisture or DGA monitors. Utilities often value factory testing documentation, reliable service support, and design details that simplify sampling and maintenance. Exact features depend on the ABB model family, voltage class, and customer specification.
