Protective relays are critical components in electrical power systems, acting as the “nervous system” that detects faults and initiates rapid isolation of affected sections. Their primary purpose is to safeguard power system equipment, maintain system stability, and ensure personnel safety by preventing damage and limiting fault propagation.
Aging switchgear is a critical concern in power systems as it directly impacts the reliability, efficiency, and safety of electrical distribution networks. Switchgear, composed of circuit breakers, disconnect switches, and other protective devices, serves to control and protect electrical systems. As infrastructure ages, maintaining or improving switchgear performance becomes essential to avoid costly downtimes, reduce risks, and meet evolving regulatory and technical standards.
