Abstract

In this paper, quantitative sensitivity analyses of various parameters of water tree and input pulse are performed using Taguchi-based design of experiment method in order to verify the feasibility of time-domain reflectometry (TDR) method for the water tree detection in the power cable. Signal to noise ratio (SNR) and percent contribution (PC) of water tree and diagnostic pulse parameters are calculated, and the parameters are identified that have high influence on the reflected pulse. The simulation software (COMSOL Multiphysics) used for the analysis is verified by comparison with the experimental results of the cable with an artificial defect. Based on the sensitivity analysis, optimal diagnostic pulse parameters are proposed for the efficient detection of the water trees.
