About this course
Explains why power systems need protection and how the main schemes work. Delegates learn about fault types, fuses and circuit breakers, current and voltage transformers, overcurrent, earth fault and differential protection, relay types, protection zones and how a scheme clears a fault, giving a foundation for later work on settings and testing.
Why this course
Staff who operate, maintain or plan networks often do not understand why protection operates the way it does, which slows fault analysis and leads to unsafe interference with settings. A clear grasp of the basics improves fault response and prepares technicians for specialist training in distribution protection and relay testing.
What delegates will be able to do
By the end of the course, delegates will be able to
- Describe common power system faults and their effects on plant
- Explain how fuses, circuit breakers and relays work together to clear faults
- Identify protection zones on a single-line diagram
- Distinguish overcurrent, earth fault and differential protection and their uses
- Check current transformer polarity and ratio for a protection application
Who should attend
Junior technicians, electricians, operators, apprentices and newly appointed engineers in utilities, municipalities, mines and industrial plants. Delegates should have a basic grasp of electricity, such as that covered in Basic Electricity.
How it is delivered
Facilitator-led sessions with single-line diagram exercises, relay and breaker demonstrations and simple fault scenario walkthroughs. It is available as a public course, in-house at your premises, or as live virtual sessions. Duration and dates are confirmed in your quote, and in-house groups can have the examples and exercises fitted to their organisation.
