Low-voltage surge protective devices - Part 12: Surge protective devices connected to low-voltage power distribution systems - Selection and application principles
Abstract
This Technical Specification describes the principles for selection, operation, location and co ordination of SPDs to be connected to 50 Hz to 60 Hz a.c. power circuits and equipment rated up to 1 000 V r.m.s.. This TS specifies requirements for protection of electrical installations against transient overvoltages of atmospheric origin transmitted by the supply distribution system including direct strikes to the supply system and against switching overvoltages. This TS gives guidance for protection against transient overvoltage due to direct or nearby lightning strokes on the structure, which is in addition to HD 60364-4-443.
