A silica gel breather design is simple and easy to install. The arrangement is placed inside the transformer conservator and includes a pot or tube filled with fresh silica gel. This is placed above the oil level, to remove maximum moisture from the air. By protecting the insulating oil, silica gel assures insulation to the entire transformer parts. Here, as the silica gel bed acts as a drying agent for the transformer insulation oil, it traps the moisture from the air released as a result of the transformer breathing. Silica gel blue and orange are the best choices for this purpose.
