Description
Medium Voltage (MV) surge arresters up to 52 kV are critical protective devices designed to safeguard electrical power systems and equipment from transient overvoltages caused by lightning strikes, switching operations, and other disturbances. These arresters operate by limiting the voltage surge to a safe level and diverting excess energy to the ground, thereby preventing insulation damage and equipment failure. Typically constructed using metal oxide varistors (MOV), MV surge arresters offer excellent non-linear voltage-current characteristics, ensuring rapid response and high energy absorption capability. They are widely used in substations, transformers, switchgear, distribution lines, and industrial installations. Designed for durability and reliability, these arresters feature weather-resistant housings, often made of polymer or porcelain, suitable for harsh environmental conditions. Easy installation, low maintenance, and long service life make MV surge arresters an essential component in modern power distribution systems, ensuring operational safety, system stability, and uninterrupted power supply across various applications.
