The development of smart grids on networks to facilitate large penetrations of micro-generation or other low carbon demand technologies will require an increased network monitoring capability. Measuring the voltage at, and current passing through, link boxes will provide some of the required information. The equipment should also be able to monitor; unbalance, power factor and harmonics.
The monitoring could be used to identify the integrity of a fused interconnection in the link box and is a step towards the provision of remotely controlled LV switches in these link boxes.
