Weather influences as well as constant load changes of transformers cause temperature fluctuations and thus a pressure equalization with the environment.
The moist ambient air drawn in during cooling leads to hydrolysis of the cellulose paper in the transformer and thus to a reduction in its degree of polymerization. GIEBEL dehumidifiers protect the transformer by effectively drying and filtering the humid supply air.
To prevent damage caused by condensation water, the use of a dehumidifier is an indispensable measure. The incoming air is dried and thus a strong reduction of the water content and the dew point is achieved. In addition to a mechanical valve system and an air filter element, these silica gel dryers make use of the regenerative capacity of the desiccant used.
