Objectives This project is split into four distinct phases: Phase 1 is to develop a retrofitable tap changer monitoring system This phase to be completed by December 2016Phase 2 is the onsite installation of 40 monitoring systems This phase to be completed by August 2017Phase 3 is the continuous data analysis and visualisation of the tap changer condition This phase to be completed by August 2019. Phase 4 is the implementation of identified trigger points into company policy and procedures. This phase to be completed by January 2020 Production and trial of a condition monitor for Tap Changers
Abstract As part of operating an efficient network Distribution Network Operators need to maximise the use of existing assets. This forms a key part of Electricity North West’s Innovation strategy for RIIO ED1. The industry has identified that there is a lack of any accurate online monitoring of tap changer condition to identify when intervention is required for repair, maintenance or replacement. The development of a leading indicator of asset condition aims to minimise the number of tap changer failures that the industry has seen over recent years by identifying early warning indicators allowing proactive intervention. The project will develop, bring to pre-production, and ultimately trial, a tap changer condition monitoring system. Other Tap changer monitoring techniques will also be explored. The project will carry out field trials to identify the optimum point at which Tap changer monitoring is required in the life cycle of a transformer. To ensure a representative sample of the transformer population is analysed, a varying number of tap changer types with different manufacturing periods, designs and operating environments will be selected. Tap changers of the same type/model will have monitoring installed at varying ages of their lifecycle to allow comparison. There is a need to identify and develop intervention and investigation trigger points through data visualisation which will feed into the future asset management strategies.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
