Training objectives:

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 results are as many questions that will be addressed. The software EMTP is used for demonstrating concepts and teaching through practical cases. Prior experience with EMTP is not required.


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


Training structure:

The training is presented in English.


Computer and temporary EMTP-RV license:

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