Результаты испытаний устройств защиты от атмосферных перенапряжений (УЗАП) для электрических сетей классов напряжения 6, 10 кВ при имитации разряда молнии в провод

Abstract

In the paper, researches are carried out on the atmospheric surges protection devices such as UZAP when exposed to lightning and switching surges. The test scheme is justified. A technique is developed for recording parameters of the discharge voltages on a test object. The results of the study the atmospheric surges protection devices of the UZAP-type mounted on a standard metal pole with the wire CIP-3 hanging on an insulating traverse. The studies provided data on the actual protective ability of UZAP–O and UZAP-K and under the action of lightning and switching surges
