Electrical engineers are seeking to assure network reliability, safety and reduce losses. These criteria should be assured with an appropriate network design. During the seminar engineers will learn how to properly maintain and design electric power networks and as a result avoid common problems and identify potential sources of losses. EA-PSM Electric Academy is practical workshop during which you will do calculations yourself with a supervision of experienced lector and will have opportunity to implement gathered knowledge on your projects.
Bring your project, make calculations with EA-PSM Electric and get insights where are the biggest loses, how to increase reliability and safety of the network.
- Design engineers
- Maintenance and design engineers
- Consultants on energy efficiency
