Patents by Inventor Wallace Vahlstrom

Wallace Vahlstrom has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Partial discharge sensor
    Patent number: 7202672
    Abstract: A RF current transformer sensor includes a first sensor portion and a second sensor portion. The first and second sensor portions are configured to define a fixed opening for receiving a test object. The RF current transformer sensor is capable of detecting current pulses between the first sensor portion and the second sensor portion for sensing partial discharges from the test object. Further disclosed is a method of partial discharge sensing.
    Type: Grant

    Date of Patent: April 10, 2007
    Assignee: Electrical Reliability Services, Inc.
    Inventors: Clarence A. Hicks, Wallace Vahlstrom
  • SYSTEM AND METHOD FOR PERFORMING ONLINE PARTIAL DISCHARGE TESTING
    Publication number: 20070046295
    Abstract: A partial discharge sensing system and method for conducting testing inside an enclosure includes a partial discharge sensor, an access port, and a signal cable. The partial discharge sensor is permanently installed at a test location inside the enclosure. The access port is configured so that an analyzer can be connected to the access port from an exterior of the enclosure. The signal cable operably connects the partial discharge sensor and the access port to enable an analyzer connected to the access port from outside the enclosure to interface with the partial discharge sensor for generating test data.
