Latest Patents
One of his latest patents is titled "Electric motor protection using a virtual speed switch." This invention addresses the detection of a locked rotor condition of an electric motor during startup. The system monitors the motor current to determine if it exceeds a predetermined threshold and whether the current decrease meets specific criteria. If the conditions are not met, a speed switch bit is set, indicating that the rotor is turning. Additionally, the system assesses the reliability of a physical speed switch and determines a locked rotor condition using both virtual and physical speed switch signals.
Another significant patent is the "Digital current differential system." This method detects faults on a power transmission line by measuring phase current samples at each transmission terminal. It involves calculating real and imaginary phaselets, determining disturbances, and re-initializing the sample window as necessary. This innovative approach enhances the reliability of power transmission systems.
