Electrical engineers seek to assure network reliability, safety and reduce losses. These criteria should be assured with an appropriate network design, however, are sometimes neglected. During the seminar engineers will learn how to properly maintain and design electric power networks and as a result avoid common problems and find loses. EA-PSM Electric Academy is practical workshop during which you will do calculations by yourself with a supervision of experienced lecturer and will have opportunity to implement gathered knowledge on your network or projects.


  • We invite you to participate in 2 days practical workshop and get 60 days FREE TRIAL for EA-PSM Electric software and consulting.
  • Bring your factories network or project, make calculations with EA-PSM Electric and get insights where are the biggest loses, how to increase reliability and safety of your network.


  • Maintenance and design engineers
  • Consultants on energy efficiency
