High voltage winding type current transformer 500 times/1 second & 800 times/1 second
ECT-1000A1 or ECT-1000A / Hirai Electric Co., Ltd.
Hirai Electric Meter Standard Product: Current Resistance 500 times/1 second & 800 times/1 second
This is a current transformer for circuits with a maximum voltage of up to 7.2kV/6.9kV. For overcurrent intensity of 500 times/1 second and overcurrent constant n>10, you can use model ECT-1000A1. For overcurrent intensity of 800 times/1 second and overcurrent constant n>5, you can use model ECT-1000A. The basic design complies with JIS C 1731-1/JEC-1201, but we can accommodate special specifications such as multiple taps or tertiary windings upon request. Place of production: Made in Japan (Kyoto).

Company information
Our company's history began on February 11, 1921, when our founder, Daisuke Hirai, established a sole proprietorship in Osaka. During World War II, we relocated to Kyoto at the request of Shimadzu Corporation, which was a military supply company for the country. In February 1952, after the war, we established the current company, built and relocated our headquarters and factory in Kyoto, and completed the technology for epoxy molded transformers. In August 2019, we opened a new production base called "Reiwa Keihanna Business Office." In 2020, we obtained ISO 9001 certification, and in February 2021, we celebrated our 100th anniversary by receiving the "66th Shibusawa Award" sponsored by the Japan Electric Association, marking a significant new step forward. Furthermore, without resting on our laurels, we are committed to continuing the fusion of the technologies and innovations we have cultivated over the years to create products that transcend traditional business fields. As a company, we aim to contribute to society by becoming an enterprise capable of supporting various "infrastructures" surrounding society and nurturing the technology and human resources that will carry "Japan's future."
