Relay protection technology plays a vital role in fault detection, isolation, and recovery, evolving with intelligent algorithms, digital equipment, and automated coordination to enhance grid reliability. These clean energy sources, connected through inverters and flexible transmission systems, are transforming traditional grids based on synchronous generators into more flexibl cant challenges to system stability. Selectivity is a mandatory requirement for all protection, but the importance of it depends on the application. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers.
