Sažetak
This paper covers several topics relating to a single problem. The primary concern is partial discharge (PD). The second concern is the influence of environmental factors on PD, which is calculated by modifying the relative dielectric constant. The third concern is the manner of presentation of the obtained data. Finally, the basic concern is predicting what will happen to the PD when a parameter changes a material’s characteristics, what the margin of tolerance is and consequently, what will happen to a dielectric-dependent system under PD. The study of partial discharge in dielectrics is important for the reliability of electrical systems of vital importance aboard vehicles. This paper examines the effect of relative permittivity change to PD in dielectric materials. The topic was previously researched, but only for cables. PD modeling is carried out in Simulink using an equivalent electrical circuit. Simulation is carried out using the Matlab programming language using an m-script and Simulink model with parameter changes executed by script loop. Another topic of this paper is how to present the voluminous data obtained (in this case 3.5 GB), dealing with large data handling and visualization. 3D graphs with multi-curve representation in the same figure are used for visualization of the obtained results.
