Course Duration: 1 Day

Course Format: Workshop format – on site or webinar format.

Target Participants: Transmission Line Asset Managers, Maintenance Planners, Line Design Engineers, Transmission Line Work Program Coordinators, Transmission Line Project Managers.

Key Learning Objectives: The course is intended to provide a thorough understanding of the elements that make up a transmission line and the inputs needed to manage these assets, as well as current industry inspection and data collection practices. Management practices that include risk assessment, asset/component replacement strategies are included, as are considerations needed to implement an effective asset management organization and methods to improve reliability.

Course InstructorCourse Highlights

George Juhn leads the Transmission Line Asset Management Interest Group (TLAM). He is a professional engineer with 28 years experience in the electrical utility industry in maintenance planning, field operations, transmission and distribution asset management, line design, rate applications and regulatory proceedings. His career spans 20 years at Ontario Hydro/Hydro One in several technical capacities including 9 years as the manager accountable for Lines and Right-of-Way Sustainment Programs and 2 years as the Director of Sustainment Investment Planning. While at Hydro One he was a CEATI program participant for 3 years and prior to Ontario Hydro he was with SaskPower in their Transmission Line Design Department. At Hydro One he led and was instrumental in the implementation of a number of transmission and distribution asset management initiatives that included a transmission lines GIS application and document structure and content for rate submissions. In addition, his accountabilities at Hydro One included maintenance planning, determination of asset replacements and risk assessments for the transmission and distribution systems, as well as the 5-year investment plan to sustain these assets.

The course covers transmission line aspects that influence maintenance and investment decisions and covers reliability measures used in the industry. The maintenance section provides inspection and diagnostic options, sample maintenance programing with cost and accomplishment reporting, industry practices, a method to evaluate maintenance program effectiveness and important condition information needed to manage line assets/components. The course includes strategies for sustainment investment planning that covers health indexing, condition based criteria, asset replacement optimization, criticality ranking of transmission lines and methods to improve reliability. The course outline is provided below recognizing that specific content can be adjusted to focus on areas of interest and types of transmission line assets under management.
