At the "41st Invention Awards" hosted by the Japan Invention Promotion Association and the Nikkan Kogyo Shimbun, Deputy Manager Kensuke Kaiuchi and two others received the Contribution Award for their invention, "Abnormal Detection Circuit for Communication Surge Protection Devices." **Award Points** The circuit for a communication surge protection device (SPD) that protects communication equipment from lightning allows for easy detection of abnormalities such as deterioration by sensing leakage current. It can detect issues without affecting the communication line by applying voltage to the SPD, and it can detect the deterioration of multiple SPDs using a single DC power supply. Since the deterioration and failure of the SPD can be monitored continuously, regular inspections are no longer necessary, leading to reduced inspection costs. Additionally, early detection and recovery of failure points become possible, which contributes to the reliability of the communication system.
