This Answer Is D
A breather is an important part of a transformer and serves a very important function. It is a simple system consisting of a silica gel breather that absorbs the moisture from the air.
It is attached to one side of the conservator, which allows air to pass in and out of the transformer tank, while also preventing moisture from entering. During the cooling cycle, the transformer oil contracts, causing the headspace to expand and allowing the transformer/OLTC to inhale the outside air.
The silica gel breather then absorbs the moisture in the air and helps to maintain a safe and dry environment inside the transformer. This ensures that the transformer components are well protected from any water damage. The breather is an essential part of any transformer and plays an important role in keeping it running properly.
