  • Patent number: 10424911
    Abstract: A device for detecting and potentially eradicating a leakage voltage from a water body comprises at least one wire sensor probe to receive the leakage voltage in the water body. The device comprises a voltage sensing circuit operable for receive the leakage voltage, and generate a voltage signal based on the leakage voltage. The device comprises a trigger circuit to receive the voltage signal, based on magnitude of the voltage signal being greater than a predefined threshold value. The trigger circuit activates an alarm circuit, and activates a circuit breaker. The circuit breaker, in response to activation of the circuit breaker, disconnects a power supply from the at least one voltage source immersed in the water body, thereby eradicating the leakage current from the water body if the leakage voltage is caused by the activated circuit breaker.
