      abstract = {Saudi Arabia’s distribution networks are entering a critical modernisation cycle as renewable energy growth, industrial expansion, electric mobility, urban giga-projects and customer expectations are reshaping the role of low-voltage and medium-voltage electrical infrastructure. The review evaluates the potential of digital switchgear modernisation to improve the reliability of smart grids in Saudi Arabia’s LV/MV networks, by integrating interoperable protection, embedded sensing, online condition monitoring, automation, analytics, and cyber-secure operational governance. This paper reviews recent research and institutional evidence from 2020 to 2025, with a focus on medium-voltage switchgear fault detection, IEC 61850-enabled digital substations, distribution automation, predictive maintenance, smart grid cybersecurity, and Saudi energy transition priorities. The goal is to develop a practical, research-based framework for upgrading legacy switchgear to intelligent assets to support renewable integration, feeder automation, outage reduction and lifecycle asset management. The review concludes that modernisation is not simply a matter of replacing equipment. It is a comprehensive transformation that needs sensorized switchgear, standardised data models, SCADA and advanced distribution management system integration, edge analytics, workforce capability, procurement reform and cybersecurity-by-design. For Saudi Arabia, the biggest reliability gains are likely to be realised where digital switchgear is prioritised on critical industrial feeders, rapidly growing urban districts, renewable interconnection points, hospital and airport networks, desalination loads and substations exposed to high temperature, dust, humidity and load variability. The study offers a staged modernisation pathway and governance matrix to align switchgear digitalisation with Vision 2030, grid automation targets, local capability building, and sustainable energy transition outcomes.},
