ENERDry Transformer Dry-Out System

Transformers and its paper insulation have a primary enemy – Water.  Water can be removed from a transformer using a  vacuum dehydration process.  Now, however an easier and less expensive method can be used to remove the water from the transformer oil and its paper insulation.  Transformers that have 5% moisture or higher can be dried to acceptable levels without taking the transformer out of service.
