Hasegawa Denki Kougyou Co., Ltd.

We manufacture equipment for the safety of electrical environments, such as ground relays. These devices protect electrical construction workers and equipment from electrical leakage fire and electric shock caused by electrical leakage in electrical equipment. We have confidence in developing hardware and built-in software for electric power measuring technology, ground fault detection systems, remote monitoring systems, continuous insulation monitoring systems, and various measuring instruments. We are a unique company in Japan for measurement of the ground electrostatic capacitance of power distribution lines. We have a track record of delivering electroscopes and phase indicators to major electric power companies, electrical construction work companies, the Electrical Safety Inspection Association, and so on.
