  • Systems and methods for monitoring components in a power transformer or the like
    Patent number: 11587727
    Abstract: The present application is directed to an electrical system including a housing configured to hold electrical components within an internal volume. In one aspect the electrical system is a power transformer. A sensor is mounted to the housing and is configured to sense a parameter associated with one or more electrical components during operation of the electrical system. A control system including a communication unit and a data processing unit is operable for analyzing the sensed parameter and comparing the sensed parameter to a predetermined minimum or maximum threshold value.
