Patent number: 6906630Abstract: A transformer management system and method involves using sensors to sense physical quantities associated with the operation of a transformer. Processing circuitry uses the sensed physical quantities to calculate values from mathematical models for representing behavior of the transformer. These calculated values are compared to threshold values and an output is generated based on the result of the comparison.Type: GrantFiled: February 28, 2001Date of Patent: June 14, 2005Assignee: General Electric CompanyInventors: Bruno Georges, Mariana Barbulescu, Estelle Gagnon, Claude Beauchemin

Patent number: 6656335Abstract: An apparatus for measuring partial hydrogen pressure in a gas stream is described. The apparatus includes a housing with micro-fuel cell sensor disposed therein. The sensor includes a sensing element having first and second gas diffusing electrodes spaced from one another with an acidic electrolyte disposed between the electrodes. A first gas permeable membrane separates the first electrode from an external gas stream. A second gas permeable membrane separates the second electrode from atmospheric air. Electrochemical charging of the first electrode occurs when hydrogen from a gas stream diffuses through the first membrane to react with the first electrode, while the potential of the second electrode remains unchanged. The potential difference between the first and second electrodes measured as current is identified to represent the sensor output.Type: GrantFiled: February 28, 2001Date of Patent: December 2, 2003Assignee: General Electric CompanyInventors: Elena Babes-Dornea, Claude Beauchemin, Renyan Qin, Jean-Christophe Marusic

Patent number: 6526805Abstract: An apparatus and method are provided for continuously monitoring the operation of electrical equipment and preventing critical operational failures. The invention quantitatively determines the concentrations of gas and/or vapor (including water) components in an insulating fluid on a real time basis. An increase of one or more detected chemical components signifies an actual or potential electrical problem with the equipment. The preferred apparatus consists of a gas extractor, an infrared gas analysis instrument, and a gas diaphragm pump. Gas and water vapor components are extracted from the insulating fluid by permeating through a membrane in a gas extractor. The gas and/or vapor components are then brought into an infrared gas analyzer by the gas diaphragm pump. A quad detector in the analysis instrument identifies and determines the concentration of three specified gases and/or the vapor simultaneously.Type: GrantFiled: August 11, 2000Date of Patent: March 4, 2003Assignee: General Electric Co.Inventors: Elena Babes-Dornea, Claude Beauchemin, Bruno Georges, Renyan Qin, Jean-Christophe Marusic
