Sažetak
The state of oil-paper insulation is the key factor for assuring a reliable operation of power transformers. The recovery voltage measurement (RVM) is one of the methods used to estimate the polarization spectrum. Analysis of the polarization spectrum is used to evaluate the condition of the insulation with respect to moisture content and aging. In this paper, a new method based on genetic algorithm (GA) is used to determine elements that represent polarization process from RVM test results. Method was successfully tested on a simple circuit and then applied on power transformer.
