The role of the oil conservator (oil pillow) ‌

The oil pillow (oil conservator) is installed obliquely above the oil tank, and there is an oil pipe connected to the oil tank. When the volume of transformer oil expands and shrinks with the change of oil temperature, the oil pillow plays the role of storing and replenishing oil. It prevents the oil from contacting with air and being oxidized and damp. The oil pillow is equipped with an oil gauge tube, and some are also equipped with a liquid level indicator to observe the change of oil level.
