摘要
The operations of digital apparatus in the information and telecommunication systems can be influenced by impulsive current of direct and nearby lightning flashes. The aim of the paper is to investigate the typical problems of selection and installation of voltage limiting SPDs, which can affect its effectiveness. In this contribution several results obtained by laboratory tests are presented. Special focus was addressed to ascertain the influence of circuit configuration where SPD is installed for the protection of sensitive apparatus against lightning overvoltages.
