This article deals with the basic mechanism of aging, that is water treeing (WT), that takes place in polymer‐insulated power cables. WT was studied by means of computer‐aided video‐enhanced microscopy, microspectrophotometry, and micromanipulation. The microdiagnostics procedure was used for cables operating in a wet environment. A phenomenological WT model aimed at estimating the residual lifetime, which considers WT as a diffusion‐with‐reaction process, was developed. The theoretical calculations were in reasonable agreement with the experimental data. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 88: 1543–1549, 2003
