Predictive Maintenance of High-Voltage GIS Assets for Saudi Smart Grids: Using Partial Discharge Monitoring, Equipment Diagnostics, and Failure-Risk Assessment under Vision 2030
- High-voltage gas-insulated switchgear (GIS) is central to compact, reliable transmission substations, yet its apparent reliability can conceal insulation defects, mechanical degradation, gas-system anomalies, thermal problems, and ageing mechanisms that become costly when detected only after failure. This review deve...
