Gas Insulated Substation Definitions and Basics

COURSE NO: E05-011
Gas Insulated Substation Definitions and Basics
Course Highlights

This online engineering PDH course presents the fundamental GIS technology, related voltages and insulation levels, GIS availability and reliability, substation arrangements and design as well as power system and financial considerations.


When determining between AIS or GIS technology, some elements alone, for example aesthetics, may be an overcoming impact on a user’s conclusion. Nevertheless, most of the time the best conclusion asks for assessing many elements and soliciting input data from many sections within an investor’s organization. It is also critical to note that the optimal substation arrangement may not be solely AIS or GIS. Sometimes a mix of the two (i.e., hybrid or mixed-technology) might be the best arrangement.


This 4 PDH online course is suitable for engineers with a desire to understand the fundamentals of Gas Insulated Substation (GIS) technology.
