What is an oil heater transformer used for?

An oil heater transformer is primarily used to maintain the temperature of insulating oil in transformers, ensuring optimal performance and longevity. By heating the oil, it helps reduce viscosity, enhancing flow and dielectric properties, which is crucial for proper insulation and cooling of transformer windings. This is particularly important in cold weather conditions where oil can thicken, potentially leading to operational issues. The integration of technologies in oil gas digital transformation has also enabled remote monitoring and control of oil heater transformers, improving efficiency and reliability.
