Seismic response evaluation of substation equipment
##plugins.themes.academic_pro.article.main##
Abstract
Electrical and telecommunication facilities are observed from the past earthquake data, as seismically weak and prone to service failure due to suddenly applied seismic loads. Among them substation equipment are the most vulnerable ones. A need for reliability of electrical equipment against vibrational hazards due to earthquakes has become prime importance. In order to meet the basic requirements regarding seismic qualification of equipment and thereby to ensure reliable power transmission, Earthquake engineering laboratory capable of performing a diverse range of seismic qualification requirements on equipment, sub-assemblies and components as per National and International standards has been established at CPRI, Bangalore. Seismic qualification of few equipment carried out are presented.
