  • Publication number: 20170102476
    Abstract: An apparatus and method for identifying physical security risks to power transmission structures and other associated assets of a power transmission system is disclosed. The apparatus includes a sensor having a sensor assembly; and a floating electrode electrically connected to the sensor and positioned adjacent to the asset being monitored.
