Switching and lightning transients course

March 21, 2018
$1200 – $1600

Training on switching and lightning transients

Training objective

The objective of this training is to get familiar with the study of lightning and switching transients for insulation coordination analysis. How to model power-systems, where to find typical data, what scenarios to run and how to interpret and verify resultat are as manu questions that will be adressed. The software EMTP is used for demonstrating concepts and teaching through practical cases. Prior experience with EMTP is not required.

Training structure

The training is presented in English.

Audience

This course was settled for a public of:

  • T&D electrical engineers
  • Consultants
  • Industry electrical engineers
  • Research personnel in industry, utilities, universities and consulting companies involved in power systems studies.
  • Post-graduated students

Computer and temporary EMTP license

Each participant will have to bring a personal computer. EMTP temporary licenses will be provided for the duration of the course.
