Abstract
Class I surge protective devices (SPDs) - for the diversion of direct lightning currents - are frequently used for the protection of low-voltage AC power systems. Nowadays DC power systems are used frequently in many telecommunication systems (e. g. mobile phone base stations). The standards which describe the requirements and the test conditions for surge protective devices [1, 2] do not address SPDs connected to DC power systems. In this paper special requirements for SPDs, connected to 48 V DC power systems are defined and described. Tests carried out with different high performance Class I lightning current arresters, connected to a newly designed test circuit, show the possibilities and restrictions for the use of these arresters in DC power systems.
