Popis
PD CLC/TS 61643-22:2016
This standard PD CLC/TS 61643-22:2016 Low-voltage surge protective devices is classified in these ICS categories:
- 29.240.10 Substations. Surge arresters
- 29.240.01 Power transmission and distribution networks in general
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).
