Underground Distribution Systems + Advanced Topics (virtual)

Course Overview

Part One: Constructing, Operating and Maintaining Underground Distribution Systems

Learn all about the effective design, construction, operation, and maintenance of underground electric distribution systems. Review the critical factors involved in the conversion of overhead systems to underground and discuss real-life examples. Discuss operations, safety, and regulatory requirements, and hear from an industry cable application engineer about underground cable reliability, failure modes, and testing methods.

Part Two: Advanced Topics in Underground Distribution Systems

Underground distribution continues to be the installation method of choice in many applications on public power systems. Although the initial installation cost of underground distribution is almost always greater than equivalent overhead distribution, it offers a wide range of advantages including greater operating reliability, lower operating and maintenance costs, better public safety, and, of course, reduced visibility and greater public acceptance.

Learn how to improve your utility’s policies, standards, and practices for planning, designing, constructing, operating, and maintaining underground distribution and hear about current and emerging industry trends.
