  • Patent number: 10891848
    Abstract: An electric field detector includes field detection circuitry configured to detect voltage in an electric field in an environment and configured to determine if the voltage meets or exceeds a voltage threshold. A warning module operably connected with the field detection circuitry is configured to provide a warning to operators in the environment. A communication module operably connected with the field detection circuitry communicates a warning notification to another electric field detector.
    Type: Grant

  • Patent number: 10877081
    Abstract: A system and method used to detect voltage by an electric field detector on equipment is provided. The equipment includes a component which is configured to come into direct contact with, or come into proximity of, a conductor of electricity, and a control system which is in operative communication with the component. An electric field detector is provided on the equipment. The detector includes field detection circuitry configured to detect a voltage in an electric field in the environment which meets or exceeds a voltage threshold. When an overvoltage is detected by the electric field detector, the control system of the equipment is configured to act by performing one of 1) activating a warning module on the equipment and 2) causing the component of the equipment to act.
