Introduction: The monitoring of the 11kV and LV networks.

Objectives: The Intelligent Distribution Network Monitoring study set out to investigate the viability of increased monitoring of the 11kV and Low Voltage (LV) networks, and to evaluate the cost benefit case associated with the deployment of a specific monitoring technology based on optical current sensors. Existing monitoring and control devices in the networks were taken into consideration, and a high level model for the costs and benefits associated with different levels of monitoring was developed. This study focused mainly on the business benefits associated with Network Planning and Network Operations. Using this model, an optimal level of monitoring has been identified.
