Training course: Ampacity and Engineering Aspects of MV and (E)HV Power Cables

Two-day training course providing an insight into calculating the ampacity of MV and (E)HV cable systems. The course also covers various important subject areas relevant to the detailed engineering of cable systems.

Your benefits

■ Understanding of the different design parameters for medium- and high-voltage power cables

■ Insight and methodologies to determine the ampacity as accurately as possible

■ Knowledge to make project specific design decisions.

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 or have a certain foreknowledge of power cables.

The course Power cables in general is recommended preparation for the in-depth courses, but not a requirement

Course topics

The following topics will be addressed:

  • Engineering aspects power cable systems and guidelines
    A general framework will be presented, highlighting topics which play a role in the design and engineering of a new underground distribution or transmission power cable system. Existing standards giving regulations, guidelines etc. will also be discussed. 
  • Cable installation design
    There are multiple options for installing (underground) power cables, all with their benefits and drawbacks. Important installation options will be discussed in detail and topics needing consideration will be identified.
  • Current rating (Continuous  and dynamic)
    Due to the variety of situations in the field, the computation of the continuous current carrying capacity of a power cable is fairly complex, despite the existence of an IEC guide in this field. How to handle special situations and identify thermal bottlenecks and how a continuous current rating is actually set up will be discussed in detail. Dynamics in the loading of underground or submarine power cables or in the power cable environment make it possible to increase the cable loading above the continuous current rating. The ins and outs of this discussion as well as the dynamic calculation of the current rating itself through to on-line dynamic rating systems in control rooms, will be discussed in detail.
  • Thermal aspects
    Estimating and measuring the soil parameters and establishing in practice. 
  • Short-circuit behavior
    The short-circuit behavior of cables will be discussed. The short-circuit current rating as well as the short-circuit forces will be covered. 
  • Magnetic fields
    A high current rating is often accompanied by high magnetic fields. Increasingly, the magnetic fields around a power cable circuit are limited in magnitude due to (inter)national regulations. This makes magnetic field design an important part of this course.
  • Asset management aspects
