  • Sensor to monitor health of metal oxide arresters
    Patent number: 10466294
    Abstract: A sensor to monitor health of surge arresters such as metal oxide arresters is disclosed. The sensor includes a housing; a sensor assembly contained in the housing, the sensor assembly including an electronics board to receive, transmit, process, and store signals; and a voltage measurement strap extending around a periphery of the housing, the voltage measurement strap being electrically connected to the electronics board and configured to measure voltage using electric field.
    Type: Grant
    Filed: January 3, 2019
    Date of Patent: November 5, 2019
    Assignee: ELECTRIC POWER RESEARCH INSTITUTE, INC.
    Inventors: Andrew John Phillips, Christiaan Engelbrecht, Robert Carlton Lynch, J. Mark Major
