Moisture Monitoring and Drying System

TRANSEC

 

 

Moisture formation in power transformers causes the insulation materials to deteriorate. More than 95% of the moisture generated in transformers is absorbed by the insulating paper. With the increase of humidity in transformers, insulation problems may be encountered and partial discharge events occur in the windings. Humidity formed in transformers affects the useful life of transformers, increases the risk of interruptions and affects energy continuity.

TRANSEC ensures the drying of the moisture created in transformers under operating conditions and significantly increases the service life of transformers.

TRANSEC CL3A; It has high moisture capacity (12 liters) for transformers with power values of 10 MVA and above.

TRANSEC CL1A; It has high moisture capacity (4 liters) for transformers with power values of 10 MVA and below.
