  • Indirect measurement method and system for monitoring and reporting leakage currents
    Patent number: 8766810
    Abstract: A system and method are provided for monitoring and reporting leakage currents caused by a load that is coupled to an AC supply line. A sensor positioned adjacent to an AC supply line senses an amperage difference between currents traveling along the AC supply line. A processor coupled to the sensor compares the amperage difference to a threshold value. A reporting device coupled to the processor generates a report at least when the amperage difference exceeds the threshold value.
    Type: Grant
