PEL/37/1 - (Disbanded 27.09.23 See PEL/37) Surge Arresters - Low Voltage

Sector: Sustainability

Categories: Resistors | Diodes | Electronic tubes | Telecommunication systems. Other | Power transmission and distribution networks | Substations. Surge arresters | Power transmission and distribution networks. General

Overview: Is responsible for UK input to the international standards for surge protective devices used in power, telecommunications and/or signalling networks with voltages up to 1000 V a.c. and 1500 V d.c. for protection against - indirect and direct effects of lightning; and/or other transient overvoltages; and for information on their selection and application. Requirements for selection and erection of SPDs in electrical installations of buildings as covered by TC 64 are excluded.
