Description
Summary:This work presents a guide for practitioners based on analysis of the fault-finding technologies used by Scottish Power Energy Networks (SPEN - one of the largest UK energy companies) for underground cables in the LV distribution network. The study involves looking at the methods and processes used with the purpose of identifying the strengths, weaknesses, opportunities and technologies within SPEN's fault-finding division. The research was achieved by a literature study as well as through numerous site visits to assess real life fault-finding scenarios. The study revealed that there was a lack of a designated LV fault-finding process based on a structured protocol, accordingly a framework was developed to create a methodical approach. This is presented in the form of a flowchart showing different scenarios of faults and their respective finding procedures. The proposed framework aims to streamline the LV fault-finding procedure for practitioners with the ultimate objective of helping utilities ensure a reduction in customer interruptions and customer minutes offline, to improve network reliability.
