Latest Patents
One of his latest patents is a method and apparatus for detecting high-impedance faults (HIFs) in electrical systems. This invention features a real-time monitoring system that utilizes sensors to track current in at least one phase of a distribution system. The analog current signature information is digitized for processing by a digital computer. The system identifies zero crossings and locates current maxima and minima. The first derivatives of these maxima and minima are computed, followed by a modified Fast Fourier Transform (FFT) to convert time domain information into the frequency domain. The transformed data is then formatted and normalized before being applied to a trained neural network. This network provides an output trigger signal when an HIF condition is probable, allowing for manual intervention or automatic deactivation of the affected network portion. The method can be implemented using conventional computer hardware and software or dedicated custom hardware such as a VLSI chip.
