    Different types of oil transformers include:

    Power Transformers: Used in high-voltage transmission networks to step up or step down voltage levels. They are typically filled with insulating oil to ensure efficient cooling and insulation.
    Distribution Transformers: These are used in distribution networks to deliver electricity at usable voltage levels to end-users. Oil-filled versions are common due to their reliability in various environmental conditions.
    Instrument Transformers: Includes current transformers (CTs) and voltage transformers (VTs) that are oil-filled for accurate measurement and protection in high-voltage systems.
    Autotransformers: A type of transformer with a single winding per phase that is partially oil-filled to handle high power levels with improved efficiency.
    Hermetically Sealed Transformers: These are completely sealed units with oil, used to prevent the oil from coming into contact with the external environment, thereby reducing maintenance needs.
    Pad-Mounted Transformers: Often used in urban areas or underground power distribution, these transformers are oil-filled and enclosed within a secure, tamper-resistant housing.
