Arc protection relays are mainly used to detect arc faults in electrical systems and protect equipment and personnel in electrical systems from arc faults. Arc protection relays can detect arcs by monitoring parameters such as current, voltage, and electric power, and quickly disconnect the power supply before an electrical fire occurs, thereby reducing the risk of fire.
Arc protection relays are usually used in medium and high voltage power distribution systems, control cabinets, transformers,generators, motors and other electrical equipment. They adopt the dual-criteria principle of arc light detection and overcurrent detection, and have the characteristics of fast protection action and high reliability.
