Sažetak
The objective of this paper is to perform the sensitivity analysis of maximum switching overvoltages in three phase transformers with considering changes in total winding capacity. Furthermore, a simulation subsystem model shown in Fig.1 for generation standard types of switching overvoltages (Fig. 2.) in the high voltage transformer has been developed in [1]. The basic idea for developed VF transformer model is given in [2, 3]. The elementary analysis, calculation and estimation parametar of switching overvoltages carachteristics is given in [4, 5]. The sensitivity of the maximum switching overvoltages in three phase transformer for the standard input overvoltages on one phase is studied [6]. The effects of changing the total capacities with the value of inductance of primary high voltages winding coil of energy transformer are specially simulated. Additionally, in the paper the initial distribution of the transient overvoltage in the transformer is analyzed. In the paper [7] measures and ways to reduce the negative effects of switching overvoltages are specifically described. Results of analysis of initial switching overvoltages for example of distribution transformer will be described.
