Transformers

getriebe Weather conditions and constant load changes of transformers provide temperature variations and thus the pressure equalization with the environment. The sucked-in cooling, moist ambient air results in the transformer for the hydrolysis of cellulose paper and thus for lowering of the polymerization.

Dehumidifiers from GIEBEL protect the transformers in which the moist air is effectively dried and filtered. In addition to a mechanical valve system and an air filter element this Silica gel dryer use the regenerative capacity of the desiccant. In this way the water in the ambient air will be removed and extends the maintenance intervals significantly.

Transformers without Adsorber

The water content inside of a transformer impacts the disruptive strength and durability.

Transformers without Absorber

Problem

Formation of condensed water

Transformer without Adsorber
1. Ambient air contains water
2. Temperature drops, moist air will be sucked in
3. Temperature rises, moist air escapes, partially remains in the expansion tank
Conclusion: Condensed water arises, oil absorbs the water, free water deposited

Solution

Usage of GIEBEL Adsorber^®

Transformer with Adsorber
1. Ambient air contains water
2. Temperature drops, moist air will be dried
3. Temperature rises, dry air escapes and regenerates the desiccant
Conclusion: no condensed water, no water in the oil, no free water

Adsorber for Transformers

Assembly	Should a horizontal or vertical adsorber be used?
Valves	Should the adsorbent be protected during downtime from unnecessary loading?
Use	Should the adsorber be refillable after complete saturation?
Use according to ATEX 2014	Will the adsorber be used in hazardous areas according to ATEX 2014?
Suitable for offshore	Will the adsorber be used in a highly corrosive environment?
Transformer volume	What is the transformer power and thus the volume of oil that needs to dry the adsorber?
