Introduction to Gas Insulated Substations

Introduction to Gas Insulated Substations

August 20, 2020 | Online :: Central time

This course will attempt to provide an in-depth understanding of Gas Insulated Substations (GIS), including design, construction, operations, and maintenance. Attendees will gain a perspective from both an original equipment manufacturer (OEM) and utility on the lifecycle journey to a GIS installation including costs and long-term ROI. As more utilities consider making a cost-benefit analysis, they must consider more factors than just real estate. It is important for prospective utilities to gain a thorough understanding of real costs, community buy-in, compliance factors, and other necessary investments to effectively create a plan forward. This course will provide updated information for utilities on these topics and plenty of room to discuss custom projects and answer questions.
