DGA analyzes the gasses dissolved in the insulating oil of transformers. The presence and ratio of gasses dissolved in the oil provide an early indication of a  fault, allowing operators to take ...

Abstract: Imbalanced distribution of fault classes poses a significant challenge in diagnosing faults in transformers using dissolved gas analysis (DGA). Oversampling and ensemble algorithms have been ...

The Calisto® R9 brings something new to the market of DGA monitors: long-term accuracy without calibration gas cylinders to manage. This breakthrough is achieved by combining a novel IR gas ...

The use of Dissolved Gas Analysis (DGA) as a method for determining the types of pending or occurring faults within power transformers has been in practice for many years. It has been proven that the ...

The presence of water in your oil will decrease the dielectric strength. The Dissolved Gas Analysis (DGA) test is another useful tool as part of your maintenance program. Examining the gasses present ...

Water treatment technologies include DGI ® Dissolved Gas Infusion Systems which utilize a patented saturator and a patent-pending channel injector to deliver supersaturated oxygen solutions and ...
