Sažetak
Low voltage LI measurement with recurrent surge generator and oscilloscope is a method used for investigating LI distribution in transformer windings or in model prototypes for various conditions. In the paper, the procedure for measurement uncertainty estimation of characteristic voltage and time quantities is given. The procedure is similar to the procedure given in the IEC 60076-2 standard for high voltage testing, but it is fully adapted to low voltage measurement with recurrent generator and oscilloscope. For the purpose of reducing the measurement uncertainties and the measurement time, a new procedure is proposed.
