ITU-T K.67 (02/2006)

عربي | 中文 | English | Español | Français | Русский
Expected surges on telecommunications and signalling networks due to lightning
This Recommendation gives the characteristics (waveshapes and peak values) of the expected surges (overvoltages and overcurrents) due to lightning on telecommunication lines of the access network and on signalling lines at customers' premises using metallic conductors. These values of the expected surges are presented as a function of a set of lightning current parameters which define lightning as the source of damage by any type of electromagnetic coupling on a telecommunication or signalling line.This Recommendation allows evaluation of the effectiveness of the protective measures (e.g., surge protective devices) that are intended to withstand the expected surge current at the installation point.
