AC Hi-Pot and Cable Commissioning Testing of Transmission Class Cables

Dates & Locations


    Starting with an introduction to cable design and insulation failure mechanisms, this course provides the basics for understanding issues which result in post installation failure of newly-installed cable.  Referencing international standards, test methodologies are compared and contrasted, reviewing the theory and practical implementation of each methodology.  Best practices are identified, and specific examples and case studies provided.  Finally, Kinectrics’ presents and shares with course attendees experiences in the field and lessons learned related to the implementation of cable commissioning testing.
