Relay protection and automation (RPA) are critical systems in electrical networks. RPA automatically detect faults and emergency situations, then take action to disconnect the damaged section of the network to protect equipment and ensure stable and reliable power supply. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. Long term cost reduction (TCO) for trainings and maintenance by reduce variety of relays A fast and selective arc fault mitigation for air-insulated LV & MV switchgear and Relion protection and control relays and sensor.
