Latest Patents
James J Regan holds a patent for a Portable Ground Fault Detector. This invention discloses a ground fault detection apparatus designed for an operating, normally ungrounded supply system. The apparatus features a periodically grounded center tap of a test impedance connected across the conductors of the system. The detector circuitry includes a charge balance circuit with low gain and wide dynamic range, which measures the amplified voltage output of a Hall effect current sensor. A preferred implementation of the circuit utilizes a charge transfer variable oscillator. Additionally, a pair of microprocessor-controlled counters respond to the oscillator, precisely measuring the average frequency over intervals maintained at approximately one second. The microprocessor calculates the fault current as the difference between current measurements taken with and without the center tap grounded. This apparatus is capable of directly measuring system currents on the order of 100 A while reliably detecting leakage currents in the milliampere range.
