  • Patent number: 8836523
    Abstract: A fault gas alarm system is disclosed. In one embodiment, the fault gas alarm system includes: a gas sensor configured to fluidly connect with an oil valve in an oil-filled vacuum-type on-load tap changer (OLTC), the gas sensor for monitoring a gas level in an oil within the oil valve; and a bi-level alarm system electrically connected with the gas sensor, the bi-level alarm system including a visual alarm indicator configured to provide a visual alarm in response to receiving an indication the gas level in the oil exceeds a threshold.
    Type: Grant
    Filed: May 20, 2011
    Date of Patent: September 16, 2014
    Assignee: General Electric Company
    Inventors: Anik Roy Trudel, Mariana Barbulescu, Yong Ng Tong
  • Patent number: 8405991
    Abstract: A heat transfer element temperature variation system is disclosed. In one embodiment, the system includes: a heat transfer element configured to thermally couple to an insulating fluid within an electrical device; an ambient temperature sensor; and a control system coupled to the heat transfer element and the ambient temperature sensor, the control system for instructing the heat transfer element to adjust a temperature of the insulating fluid within the electrical device based upon a temperature indicator from the ambient temperature sensor.

  • Patent number: 6906630
    Abstract: 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.
