Impact of Steep Front Short Duration Impulses on Power System Apparatus and Insulation: A Critical Review

摘要

This paper presents a review of an extensive literature search performed to determine the extent of prior work in the area of steep fron short duration (SFSD) impulses and their impact upon electric power system insulation. The search covered experimental data and reports, theoretical or statistical modes of insulation response to SFSD pulses and anomalous insulation failures which may be attributed to SFSD pulses. A subjective ranking or representative types of transmission and distribution apparatus in terms of perceived susceptibility to damage by SFSD impulses and replacement/repair costs is provided. Specific areas involving SFSD impulses and insulation systems which warrant additional investigation are identified. 31 refs. (ERA citation 11:004121)
