Full Description

Scope

This standard applies to surge protective devices designed for application on the low-voltage ac mains (1000 V rms and less, frequency beetween 48 and 62 Hz.) This performance standard applies to surge protective devices intended to be connected at locations between and including the secondary terminals of the distribution transformer and the main service entrance panel. Surge protective devices limit transient overvoltages by diverting surge current and subsequently automatically interrupting the passage of follow current.

Purpose

Secondary arresters have been used since 1940 to protect the secondary winding of distribution transformers, kw.h meters, and electrical loads downstream from breakdown of insulation during lightning strikes. Performance criteria for secondary arresters are included in standards for performance of high voltage arresters IEEE C62.1-1989 and IEEE C62.11-1993. With the proliferation of electronic equipment installed inside buildings, the emphasis has shifted away from protection of insulation on wiring devices to vulnerable electronic equipment. The purpose of this standard is to address that changed emphasis while, as far as possible, harmonizing with relevant international standards.

Abstract

New IEEE Standard - Active.Surge-protective devices designed for application on the low-voltage ac supply mains (1000 V rms and less, frequency between 48 Hz and 62 Hz) are covered.
