Statistical Analysis of Breakdown Voltage of Insulating Liquid Dopped with Surfactants

This article presents the research process and statistical analysis of selection an appropriate type surfactant to be added natural ester oil MIDEL eN 1204. The tested parameter was breakdown voltage. following surfactants were tested: Triton X, ROKwinol80, oleic acid. With obtained results, we can conclude that with best properties, compared basic sample, have acid, also high levels voltage characterize a sample X concentration 2%. Statistical performed using MATLAB program.
