What are the technical aspects of transformer oil circulation?

The technical aspects of transformer oil circulation involve maintaining optimal temperature and ensuring effective cooling of the transformer. This is achieved through a closed-loop system where oil circulates via pumps, transferring heat away from the core and windings to radiators or heat exchangers. Key factors include oil viscosity, flow rate, and the design of the cooling system, which must be tailored to the transformer’s capacity and operational conditions to prevent overheating and ensure reliability.
