Latest Patents
Harrison holds a patent for a ground fault detection circuit. This current monitoring circuit receives its input from the secondary winding of an annular core transformer, through which the current-carrying leads being monitored extend. The design incorporates a resistor and capacitor connected in series between the secondary winding and an AC amplifier, forming an RLC band pass filter. This configuration minimizes the circuit's sensitivity to noise outside the band of frequencies of interest. Additionally, the circuit's sensitivity to temperature changes due to fluctuations in inductance is reduced by selecting an inductance value that remains above a critical level.
