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.

Air demoisturizer for oil-insulated transformers, chokes and tap changers

A liquid level indicator for an oil-filled transformer, power choke or tap changer in which a sensor part has a float which rises and falls with the oil level and rotates a sensor shaft and the sensor shaft is coupled to an indicator shaft on which a pointer is provided to cooperate with a dial. The gauge also includes a contactless angle encoder operating with a magnetic hub and coupled to the indicator shaft for outputting a signal representing the oil level.
