Application of Substation SCADA Data for Circuit Breaker Maintenance Optimisation and Network Reliability

Aged electricity substations with non-intelligent, non-IEC61850 devices are still in operation and in some cases financial and resource constraints may prevent their upgrade. The lifespan of these assets continues to be extended, while maintenance spending has remained flat or decreased, even as public expectations for network reliability continue to rise, Moreover, these substations are predominantly in remote/rural areas, low capacity, low utilisation but high in maintenance costs to operate the network reliably.
