SIMULATION OF THE REAL SHORT-CIRCUIT IN THE DISTRIBUTION NETWORK WITH MATLAB
KOMUNALNA ENERGETIKA / POWER ENGINERING, 27
The article deals with the simulation of the real short-circuit in the distribution network with Matlab. The purpose is to show how in simulation of the real short-circuit in software package Matlab determine model parameters. Assuming that we know all the parameters of network elements can in principle produce a model of the distribution network that is completely identical to the actual network. Nevertheless, we have in any real short circuit variables that need to be taken into account in the simulation. In conclusion, is by comparing the timings of effective short-circuit currents in single-phase, two-phase and three-phase short circuit, illustrate the correlation of simulation results and actual measurement.

Electric Field Strength of the Medium Voltage Post Insulator with Different Number of Ribs
KOMUNALNA ENERGETIKA / POWER ENGINERING, 239
The paper describes the designing of a medium voltage post insulator. The insulator model was designed in Matlab software and calculations of the electric field were in Elefant software. The emphasis is on the external shape of the insulator. The paper presents examples of the insulator with different number of ribs and their influence on the insulator’s electric field strength.
