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.
