The Risk of Lightning Losses in a Structure Equipped with RTC Devices According to the Standard EN 62305-2.2008

Incorrect adjustment of railway traffic control devices (rtc) to the specificity area in terms lightning density may result their damage by lightning-caused electromagnetic pulses. An associated risk assessment, as standard analyses strength rtc devices, should be made. However, manufacturers typically do not perform tests with respect such high overvoltage conditions. Particularly case EN 62305-2 standard, new rail usually carry out analyses. In this paper, an analysis vulnerability caused discharges for a selected structure, including signal box equipped digital is presented. The necessity conducting demonstrated. A part track where occur was analyzed. results obtained use DEHN Risk Tool software and based on (2008, Lightning protection. Part 2. management) are Due fact that included current three documents were adopted analysis: two editions EN/IEC (from 2008 2012) recommendations ITU-International Telecommunication Union ITU-T K.39 (10/1996). presented performed according version chosen device.
