(a) absorbing heat.
(b) ionizing air.
(c) absorbing moisture.
(d) cleaning oil.
Answer
(c) absorbing moisture.
Explanation
- The chemical used in the breather of the transformer is Silica Gel. The function of a breather in a transformer is to absorb moisture from the air. The silica gel is a desiccant.
- It has the good properties of adsorbing and holding water vapors.
- Therefore Silica gel is employed in the breather of the transformer.
- Silica gel is the chemical that is employed in the breather of a transformer due to its strong affinity for water molecules.
- The basic function of Breather in the electrical transformer is to absorb moisture and silica gel perfectly fulfills this need.
