Overview
EN IEC 62271-109:2019 is a European standard harmonized with the international IEC 62271-109:2019, developed and maintained by the European Committee for Electrotechnical Standardization (CENELEC). This standard addresses high-voltage switchgear and controlgear, specifically focusing on alternating-current (AC) series capacitor by-pass switches designed for outdoor installation. These switches are intended for three-phase systems operating at frequencies of 50 Hz and 60 Hz on electrical systems with voltages exceeding 52 kV.
EN IEC 62271-109:2019 provides essential guidelines for the design, testing, installation, and operation of by-pass switches used in series capacitor banks of high-voltage AC systems, ensuring safety, reliability, and compatibility in power transmission and distribution networks. It also covers auxiliary equipment and operating devices linked with such switches.
