Will DryKeep extract the dissolved gases when it extracts the moisture?
DGA Fault analysis is widely used as a tool to carry out condition monitoring on transformers and has become a useful early warning system to eliminate catastrophic failure. We were very much aware of the value of the dissolved gas analysis (DGA) in determining the condition of the transformer and wanted to insure that DryKeep would not extract enough of the gasses to distort the results of the DGA. Experiments have shown that the Acetylene gas content of the oil flowing directly out of the DryKeep system was reduced by 20 percent. Carbon monoxide was reduced by 25 percent. The moisture content was reduced by as much as 90 percent. However, the method of circulation of oil through the DryKeep system is on the basis of continuous partial circulation of the main oil system in the transformer. The result is that the DryKeep system can remove only a small percentage of acetylene gas from the oil. We must bear in mind that the maximum measured flow rate of the DryKeep system is only 90 lite
