DryKeep USA will show its DryKeep™ on-line moisture removal system for power transformers. Developed by Rotek Engineering, a division of Eskom, the power company of sub-Sahara Africa, the system uses molecular sieve dry-out (MSD) acrylic “sponges” that continuously remove water from the oil and paper insulation as the oil passes through the cartridges. The re-chargeable saturated cartridges can be quickly changed out while the transformer is in service. Transformer monitoring data is preserved as moisture is removed. Dehydration is continuous, as opposed to prolonged buildup followed by periodic dry-outs.
