Gas Insulated Substations
Regulations, Operations & Maintenance
January 29-30, 2018 | Washington, DC
Overview
Faced with increasing demands for reliability, improved aesthetics and security, the adoption of gas insulated substations (GIS) by North American utilities is rapidly increasing. Companies elect to use GIS because of the increased load and limited space present in the urban areas. Often, building new substations or increasing capacity is difficult because land is either not available or is prohibitively expensive.
This conference will address regulatory, technical and business considerations for GIS. It will review GIS technology and detail current design trends and maintenance solutions for gas insulated substations. Utilizing both technical presentations and case studies from leading utilities, attendees will be provided with a sound understanding of GIS capability as well as real-world examples involved in selecting and constructing GIS substations.
In addition, experts will cover technical and commercial capabilities, review greenhouse gas issues, illustrate how to replace aging infrastructure with GIS, and review considerations for selecting GIS. They will discuss various special challenges involved in GIS, including SF6 leak detection, GIS commissioning, constraints, and challenges from an engineering perspective.
This event will conclude with a tour of Pepco’s brand-new Waterfront substation.
