Abstract
An air demoisturizer for an oil expansion vessel of an electrical power unit like an oil-filled transformer, tap changer or choke, has a heating element in the body of absorbent and utilizes a heat-regeneratable absorbent which is cut off by a moisture detector from the oil expansion vessel when the absorbent is saturated and is thermally regenerated. The demoisturizing column is provided in line with an oil receiver through which the dry air is passed before reaching the oil expansion vessel.
