Latest Patents

Sugimoto holds a patent for a "Ground Fault Current Limiter and Method of Limiting Ground Fault Current." This invention involves a ground fault current limiter where reactors are connected in series to a neutral point. The device compensates for capacitances to ground of power switches that can turn ON/OFF at high speeds. It detects ground faults by analyzing the phase difference between zero-phase sequence current and zero-phase sequence voltage during sampling. The optimal compensation quantity of capacitances to ground is computed based on these parameters, allowing for controlled ON/OFF switching of the reactors to correspond to the compensation quantity. He has 1 patent to his name.
