What are the key features of ABB oil filled transformers?

ABB oil filled transformers are typically known for utility grade design options, strong standards compliance, and broad configurability across voltage classes. Common features include sealed or conservator tanks, a choice of tap changer arrangements, robust bushing systems, thermal design for specified temperature rise, and provision for monitoring such as oil level, top oil temperature, winding hot spot, and optional online sensors. Utilities also value comprehensive factory testing documentation and service support networks.
