Abstract
This paper presents a study from EDP Distribuição and LABELEC, whose purpose was to develop a methodology to estimate the remaining useful lifetime (RUL) of 86 High Voltage (HV)/ Medium Voltage (MV) power transformers in service, based on data from the DPv (viscometric degree of polymerization) measurements of insulation paper of 9 HV/MV power transformers intended for scrapping.We present the methodology developed during the study and the final results.
