Training course: Power Cables in General

This general course covers all the important aspects of MV and (E)HV cables and their accessories.

A relatively large number of cables are buried underground. This means that many people will be involved with (underground) power cables professionally, and that associated knowledge is a key requirement. This basic course, Power cables in general, covers all the relevant aspects relating to power cables - not always down to a detailed level (specialized courses are available for this purpose), but especially in a related context. This means the course provides a good overview of all the elements that are of interest, as well as the options available for approaching or solving certain problems.

For whom?

Anyone involved (or to be involved) with power cables in the course of their daily work. It is recommended that the participants hold at least a Bachelor of Engineering degree.

Course topics

The following topics will be addressed:

  • Design parameters
    The course deals with the theory that is relevant to cables and its practical implications. We calculate the electrical fields, the capacity, cable losses and also look at subjects such as transmission line models and the skin effect. 
  • Materials
    The common insulation materials for cables are paper and extruded materials (plastics). The properties of these  materials in particular and the influence  of these properties on the performance  of the cable are discussed.
  • Types of cable
    The cable types currently in use are discussed in relation to the various voltage levels. Additional attention is devoted to the water tightness of cables. Furthermore, additional specialized cable types are discussed, such as submarine cables, HVDC cables and superconducting cables.
  • Cable manufacture
    An overview of the factory. How is a cable manufactured and what are the implications of this in terms of use?
  • Cable joints and terminations
    There are many types of joints and terminations in use, and a great deal of (practical) experience has been gained with them. However, one thing is certain: accessories remain an area of special concern. In this part of the course we cover this area in more detail and we are introduced to the full range of existing technologies. In addition, the vulnerabilities of joints and terminations are addressed.
  • Cable installation
    The installation of cables itself pre-determines many future conditions. In view of the extended life of cables, a detailed study of the installation and everything connected with it, such as special placements, overvoltage, connections, current load, grounding, cross bonding, etc., is called for. The current load is particularly discussed in a coherent context. The ‘Ampacity and engineering aspects of power cables’ course deals with this aspect in detail.
  • Ageing
    The course provides a summary of the ageing mechanisms that apply to cables, joints and terminations, the physical phenomena and the influence of the surroundings and temperature. The causes of faults are also discussed. The course ‘Ageing, quality assurance, testing, diagnostics and failures of power cables’ addresses this theme in further detail.
  • Testing cables during the production phase
    The different types of tests conducted  to complete the design and production phases are covered in general. In addition, the course addresses the technical background and the current standards and norms. The course ‘Ageing, quality assurance, testing, diagnostics and failures of power cables’ addresses this theme in further detail.
  • Testing cables during the operation phase
    This section provides a summary of the various tests that can be conducted in the field. The acceptance tests and various forms of diagnostic testing are discussed. This subject matter is subdivided into potentially destructive and completely non-destructive testing and into off-line and on-line testing. We will take a look at the value of all of these tests and the way in which the tests should be applied. This section also provides a general overview of fault localization. The course ‘Ageing, quality assurance, testing, diagnostics and failures of power cables’ addresses this theme in further detail.
In some cases, a visit to the KEMA labs may be part of the training program. (note: not applicable for online training)

A few responses from previous participants

  • ‘‘Well planned course for those who aim to achieve a complete overview from theory, installation and maintenance on power cables systems.’’ - Giorgio Gallettini, Vattenfall Vindkraft AB
  • ‘‘The Power Cables in General course is held by real experts with long experience and good teaching skills. I liked very much the completeness of the course, from theoretical basics to installation and maintenance/testing. In addition, the course was enriched by laboratory visits.’’ - Christian Möller, Tractebel Engineering GmbH
  • ‘‘All aspects of power cables are in the course, which helps to understand the whole playing field of these important energy-connections.’’ - Remco Brandenburg, Bilfinger Tebodin Netherlands B.V.
  • ‘‘Good course that did meet my expectations.’’
  • "This is an excellent course designed to provide a complete overview and useful practical information about the power cables. A must for managers who want to avoid theoretical courses."
