Failure modes, testing, diagnostics and remaining life assessment of HV and EHV power cable systems training course
This is a two day course. It focusses on the cable situation after having been installed. It covers items like degradation mechanisms, tests after installation and tests and diagnostics during service operation, remaining life assessment, failure modes and failure investigations of HV and EHV power cables and their accessories (both AC and DC) - all within the context of, and linking to, quality assurance and control.
After installation of cable systems, the first question is how to test this situation before the cable systems are taken into service. The next question is how to monitor the cable system’s performance. What are the expected degradation mechanisms that can affect cables and its accessories? What is the rate of progression of these degradation processes? Do they all result in failure? What methods are available for diagnosing these degradation mechanisms in the field? Which ones can be applied off-line and which ones on-line and are these off-line tests potentially destructive or not? And how reliable are test results? What is the relationship of all this to safeguarding quality and reliability? What are the potential weak spots and pathways towards a failure? And in case of a failure, what is the best way to investigate its cause?
This in-depth practical training course is part of a series of courses on power cables, consisting of a general course, Power cables in general and multiple day courses, providing more detailed information on the following topics:
- Ampacity and engineering aspects of power cables
- Failure modes, testing, diagnostics and remaining life assessment of MV power cable systems
Subjects:
• Cable types and accessories (AC, DC, also submarine)
• Quality assurance / Maintenance strategies / Asset management
• Ageing mechanisms and failure modes
• Testing after installation
• Testing and diagnostics during the operational phase
• Remaining life methodologies and assessment
• Failure investigations
• Exercises with practical case studies
Target Audience:
Anyone involved (or to be involved) with power cables in the course of their work. It is recommended that the participants hold at least a Bachelor of Engineering degree or have a certain foreknowledge of power cables. The Power cables in general course is a recommended preparation, but not a requirement.
Next to underground power cable courses, DNV also offers several courses in the field of HVDC and submarine power cables:
On request, Energy Academy can also provide an in-company training (content, location and duration of the course can be adapted to the client’s wishes). Please contact us for more information.
