OTSHVEP001 ADVANCED HV ELECTRICAL PROTECTION - Electrical (1)

Advanced High Voltage Electrical Protection (Faraday Centre) (Ref:OTSHVEP001)

Course Objectives

To gain a detailed understanding of HV Protection.

Course Description

This course is designed to increase the trouble shooting skills and fault diagnostic processes of engineers and maintenance teams on HV Generation and Distribution systems. The practical elements of the course centre on advancing the candidate’s knowledge of protection systems. The course will progressively move toward advancing the candidate’s knowledge of the faults and their rectification on a ranging of electrical systems.

Who Should Attend

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.

Pre-Requisites

All Attendees should have a sound power generation and electrical background.

Course Outcome

At the end of this course you will be able to troubleshoot high voltage systems.
