Scope
This standard covers the application of gapped silicon-carbide surge arresters (see ANSI/IEEE Std C62.1-1984 [1])
1
to safeguard electric power equipment against the hazards of abnormally high voltage surges of various origins. Such
overvoltages may cause ßash-overs and serious damage to equipment, thereby jeopardizing the supply of power to
users. It is essential to prevent this by the proper coordination of surge protective devices with the insulation strength
of the protected equipment.
The subject is a broad one with many ramiÞcations, and it would require a volume of considerable bulk to explain all
possible cases in detail. Section 3 of this standard covers the basic cases for stations used to supply and switch electric
power transmission, subtransmission, or distribution feeders. Information is included in Section 4 on application of
arresters for protection of overhead distribution systems, both open-wire and spacer cable; underground system cables;
all distribution transformers; and other electric distribution equipment.
Step-by-step directions toward proper solutions for various applications are provided. For many cases the prescribed
steps are adequate. Complex situations or special situations requiring study by experienced engineers are described,
but speciÞc solutions may not be given. These procedures are based on theoretical studies, test results, and experience.
