Nowadays, Gas Insulated Switchgears and Substations are playing basic roles on distribution and transformation of electrical energy. 230 KV GIS of Iran LNG Company is designed to distribution electrical energy around the plant to achieve liquefied natural gas. These Gas Insulated Switchgears include 24 BAYs and are used specially to liquefy natural gas. Maintainability and availability of electrical switchgear are therefore essential for Iran LNG Company consequently for all of oil and gas projects in Iran’s south Pars. Extensive considerations and comparative attention to above GIS, indicates that using of GIS in the south pars project provides very reliable and capable energy distribution, and in this case times for component replacement are specified.
