TRANSEC is a system to dry power transformers of all sizes. The problem of wet transformers is already well-known. Due to moisture and oxygen, the insulation paper within the transformer degenerates. One of the products of this chemical process is H2O. While only a small part of the moisture is absorbed by transformer oil , more than 95% of the moisture becomes diffused in the tons of insulation paper. Depending on the percentage of moisture, the aging of the transformer increases and failures such as flashovers between the windings, treeing, and creeping discharges occur.
Temperature changes of the oil during the operation even increase the risk of an outage. Once the oil in the transformer gets dried by TRANSEC, it dehumidifies the insulation paper and returns back again to the unit. Using this cycle effect, TRANSEC keeps the insulation paper permanently dry, ensures a faultless operation and elongates the life expectance of the transformer significantly.
Compared to other solutions, the transformer can be dried during its operation. There is no need to transport or switch it off.
