All Attendees should have a sound power generation and electrical background. At the end of this course you will be able to troubleshoot high voltage systems.

To gain a detailed understanding of HV Protection.

Electrical Engineers and Technicians who have the responsibility for maintaining local electrical operating networks. Engineers who need to trouble shoot and understand protection systems on many different systems and need to advance their knowledge and skills of these systems.

This interactive Training will be highly interactive, with opportunities to advance your opinions and ideas and will include;

• Lectures
