This paper critically reviews the electrical tree growth measurement techniques commonly employed. The paper continues, describing the development of a user friendly software tool using MATLAB. This tool quantitatively evaluates a host of electrical tree growth images using various techniques, including fractal index, width length ratio and intensity frequency analysis. The software methodology, associated implementation challenges as well as salient software features are discussed. Estimation of three dimensional models from two dimensional digital images is also addressed in this paper. The performance of the embedded techniques for electrical tree growth measurement, as well as the image processing algorithms utilized in the developed software tool, is qualitatively and quantitatively reviewed. Preliminary results from the developed software on electrical tree growth images highlight the potential to improve the accuracy of deductions, from investigations on factors influencing electrical tree growth.
