Autor: Ninoslav Simić, Ranko Jasika, Jovan Mrvić, Petar Vukelja, Goran Lepović

Publikováno v: Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", Vol 26, Iss 26, Pp 177-194 (2016)

The goal of this paper is to introduce a procedure for risk assessment of insulation failure due to storm surges. The simulations were carried out in ATP / EMTP software, which allowed the use of the Monte Carlo method for the statistical analysis of

Insulation co-ordination for continuous operating voltages and temporary overvoltages

Autor: Zlatoje Zdravković, Jovan Mrvić, Petar Vukelja

This paper presents an approach to the insulation co-ordination of electric-power installations in the scope of the continuous operating voltages and temporary overvoltages; this approach opens the possibility to calculate the necessary required with

Disruptive discharge risk and reliability parameters of high-voltage electrical power facilities

Autor: Jovan Mrvić, Zlatoje Zdravković, Petar Vukelja

This paper presents an approach to the calculation of disruptive discharge risk and the reliability parameters for insulations of high-voltage facilities. It starts from overvoltages on individual insulations occurring as the consequence of the relev
