Conductor recognition using semantic segmentation

11.00am — 12.00pm , 19 July 2022

Overview

About the event 

Worldwide electricity distribution companies are moving towards risk-driven network replacement and maintenance strategies, and part of the risk assessment is to evaluate or estimate the asset condition. Unison has an ageing overhead conductor fleet consisting of over 4,200 km of high voltage lines, there are approximately 500 km of 7/0.064 Plain Hard-drawn Copper (PHC) 11 kV conductor in the fleet. The conductor has low tensile strength and an aged installation profile. Research that Unison conducted in 2018 identified the conductor’s visual appearance as a key indicator for condition assessment – hence Unison is currently developing a system that can use conductor images obtained by drones, to automatically evaluate the appearance and condition of the conductor.

This presentation will show the process followed to use machine learning and semantic segmentation to recognise/identify the overhead conductor region of interest in images with natural backgrounds. Such segmentation of the conductor is a required first step before evaluating the conductor appearance and condition, which also uses automated machine learning techniques
