Organization: IEC
Publication Date: 1 June 2015
Status: active
Page Count: 134
ICS Code (Power transmission and distribution networks): 29.240
ICS Code (Substations. Surge arresters): 29.240.10
ICS Code (Power transmission and distribution networks in general): 29.240.01
scope:

This part of IEC 61643 describes the principles for the selection, operation, location and coordination of SPDs connected to telecommunication and signalling networks with nominal system voltages up to 1 000 V r.m.s. a.c. and 1 500 V d.c.

This standard also addresses SPDs that incorporate protection for signalling lines and power lines in the same enclosure (so called multiservice SPDs).
