Condition monitoring of power cables: is there anything new to say?

A lot has already been said about power cables and the best way to assess and monitor their condition. But the information that circulates online is not always impartial nor up-to-date. With this webinar, our experts want to share tips and opinions in an objective and independent manner.

Date: 26 May 2020


Participation is free of charge

Not available on the day of the webinar?

No problem, you can register anyway and we will send you the slides afterwards. 


Webinar programme

PART 1 - Power cable degradation: what you need to know

We limit theory to the absolute minimum, but we do need to spend some time on degradation, how power cables age, and which external factors have an impact on lifetime.

PART 2 - Assessment and monitoring: what works and what doesn’t …

… and in what situations? We take you through the following techniques:

  • Time Domain Reflectometry (TDR)
  • Outer sheath testing
  • DC insulation (resistance) testing
  • AC insulation / tan delta testing
  • Dielectric spectroscopy
  • Partial discharge measurement

For each technique, we look at:

  • How to carry out measurements in the best conditions
  • What information each test gives us
  • What can go wrong during measurement or when interpreting the results

That said – if you have specific questions, send it to us before 15 May and we’ll do our best to address it during the webinar.

This webinar is an opportunity for you to ask questions

You are most welcome to ask questions during the webinar, and why not to bring specific cases for discussion. Our experts will offer their opinion, and questions that were not answered during the webinar will be addressed by email after the webinar. Questions can be asked in English, French or Dutch.
