  • Publication number: 20120312515
    Abstract: In accordance with one embodiment of the present invention, a panel for a transformer radiator includes a pair of substantially-rectangular panel sheets joined together to form a plurality of internal fluid channels, each fluid channel including an inlet and an outlet, and a plurality of pin fins disposed on at least a portion of at least one external surface of the panel sheets.

  • Publication number: 20060292710
    Abstract: A probe cell monitors conditions within electrical power transmission and switchgear apparatus to detect degradation of stressed components. The probe cell is a hardware simulation of components of a specific unit of electrical power apparatus, including electrodes between which an electric field gradient is established. The probe cell electrodes accumulate contamination at a rate related to accumulation rate on components of working apparatus. In a typical embodiment, a probe cell installed within an enclosure shares the insulating, hydrocarbon-based immersion fluid of the apparatus. Because the probe cell can be invasively tested and results recorded as often as desired without deenergizing the actual apparatus, degradation of the apparatus can be predicted with high confidence, avoiding unnecessary maintenance as well as unexpected catastrophic failure. Potential reduction in unproductive preventive maintenance while avoiding emergency repairs can offset probe cell cost.

  • Patent number: 7119646
    Abstract: An apparatus for controlling the temperature of a core of a transformer is provided that includes a core, a shield surrounding the core, a cast formed between the core and the shield, and tubing positioned on the shield. The cast directs heat from the core to the shield and cooling fluid is directed through the tubing to cool the shield.

  • Publication number: 20050016758
    Abstract: A method and apparatus for connecting high voltage leads to a super-conducting transformer is provided that includes a first super-conducting coil set, a second super-conducting coil set, and a third super-conducting coil set. The first, second and third super-conducting coil sets are connected via an insulated interconnect system that includes insulated conductors and insulated connectors that are utilized to connect the first, second, and third super-conducting coil sets to the high voltage leads.

  • Publication number: 20050000356
    Abstract: A dehydrator breather is provided that includes a vessel, a desiccant container, a valve housing coupled to the vessel, and a vent assembly coupled to the valve housing. The vent assembly includes screened ports disposed along a vertical axis of the vent assembly body that allow air to enter and exit the dehydrator breather. The vent assembly, along with a filter placed between a desiccant container and the valve housing, individually and jointly, prevent desiccant that escapes the desiccant container from clogging the valve assembly.
