LV & 11kV Networks
Overhead line faults and the resultant Customer Interuptions/Customer Minutes Lost (CI / CML).
FPIs are currently used by Scottish & Southern Energy Power Distribution, however they do not communicate their status through GSM. In the event of a fault beyond the FPI, indication of the passage of fault current is made by the flashing of a bulb. This means that an operative must physically visit the site of installation of the portable FPI to determine the status of the device. Use of a GSM enabled FPI (GSM-FPI), would allow engineers to be informed in a more efficient manner, leading to a better deployment of staff and reducing the period of time that customers are without supply.
This project will trial and evaluate the use of the Nortech POLESTAR Fault Passage Indicators as a means of reducing CI/CML penalties, incurred on the 11kV overhead line network
