Title: Innovations by Tomokazu Nishigaki
Introduction
Tomokazu Nishigaki is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of electrical engineering, particularly in the area of electricity leakage detection. With a total of 3 patents to his name, Nishigaki's work has advanced the safety and reliability of electrical systems.
Latest Patents
Nishigaki's latest patents include a direct-current electricity leakage detection device and an electricity leakage detection device. The direct-current electricity leakage detection device features an excitation unit that applies an excitation voltage to an excitation coil, with the voltage level alternately changing between a first high voltage value and a first low voltage value. This device includes a comparison circuit that outputs a comparison signal based on whether a detection voltage is greater than, equal to, or less than a threshold voltage. The voltage switching circuit then adjusts the excitation voltage according to the comparison signal.
The electricity leakage detection device incorporates a first decision unit that outputs a signal based on a corrected voltage signal relative to a threshold value. It also includes an excitation unit that applies an excitation voltage with a specific frequency. A DC component detection unit measures the magnitude of a DC component, and a second decision unit outputs a signal based on this measurement relative to another threshold value.
