About the course
All modern industrial and commercial business processes rely on a continuous and secure supply of electricity; electrical circuit protection plays a vital role in achieving this. In order to prevent severe supply disruption and minimize health and safety risks, systems need to be protected from the consequences of overload and fault conditions. The course is ideal for delegates with a background in electrical power systems.
This course will:
- Explore how electrical circuit protection systems function and the role they execute
- Highlight the importance of electrical circuit protection, examining the protection of all major plant by
- providing an insight into selecting circuit settings and resolving protection issues
- Offer practical workshops to reinforce material covered on the course.
- Why do we need circuit protection?
- How can protection be achieved?
- Protection of plant and equipment
- Protection of site personnel
- Protection by system design
- Faults (causes, types)
- System arrangements that influence protection.
