  • Fault gas alarm system
    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
  • Heat transfer element temperature variation system
    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.
