Title: Masaki Kozai: Innovator in Power Supply Systems
Introduction
Masaki Kozai is a notable inventor based in Musashino, Japan. He has made significant contributions to the field of power supply systems, holding a total of 2 patents. His work focuses on enhancing the safety and efficiency of electrical systems.
Latest Patents
Kozai's latest patents include a "Power supply system, ground fault detection method and program." This innovative feeding system is designed to provide power to a load using a single device that maintains a high-resistance neutral point between the feeding line and the earth. The device acts as a ground fault overvoltage detection type of ground fault detector. When a ground fault is detected, it sends a signal to a control device, which then instructs a breaker to perform the necessary action.
Another significant patent is the "Power supply system, protection coordination method and program." This system feeds power from a power unit to a load through a feeding line. It includes a protection device that operates when a current reaches a predetermined level, a monitoring unit that checks for accidents in the feeding line, and a gate block unit that halts power supply if an accident occurs that prevents the protection device from functioning.
