Latest Patents

Hidenobu Koide's latest patents include two distinct designs for optical current transformers. The first patent describes an optical current transformer that utilizes two independent optical sensor units. These units receive incident light beams, which are then combined to produce a measurement signal proportional to the current flowing through a conductor. The optical sensor units are designed as U-shaped bars made from Faraday effect glass, featuring rectangular cross sections and 45-degree reflecting surfaces at the corners.

The second patent also focuses on an optical current transformer, which measures current by transmitting a light beam around a current-carrying conductor. This design incorporates four Faraday effect glass rods arranged in a rectangle, creating a through hole for the conductor. The system includes three optical path changing pieces that redirect the light beam among the glass rods. Additionally, two substrate plates with through holes for the conductor sandwich the glass rods and optical path changing pieces, allowing for thermal expansion and contraction.
