What you'll learn:
- understand all of the key elements & principles of an electrical protection system
- Draw what an electrical protection system looks like
- Explain how a differential relay operates
- Understand the operation of no load and off load tapchangers
- Know what alarms a transformer generates
- Understand the difference between ONAN, ONAF and OFAF transformer cooling systems
- Know how to size a battery
- Be able to draw a basic DC system for a substation
- Know what circuit breaker failure is
- Understand how a circuit breaker auto-reclosure system works
- Know how to synchronise a circuit breaker
- Understand how a substation SCADA system operates
- Know the difference between star and delta windings on a transformer
- Understand how the transformer vector group affects the system
The aim of this course is to introduce all of the basic principles associated with these complexsystems.
The course will go into detail for the following key topics :-
Show how a substation DC systems operated and how the battery is sized
Look at the key elements of a circuit breaker protection scheme
Introduce the principles behind circuit breaker failure protection and show what action needs to be taken.
See how circuit breakers can be re-closed after a fault andoutline the systems involved
Introduce the principles behind synchronising, show what parameters need to be checked and how the systems operate.
Go into detail on the main features of transformers, including vector groups, tapchangers, cooling systems, controls / alarms& protection systems
Introduce the basic principles and systems associated with SCADA systems
By theend of the course the studentwill be able to identify all of the key components of a protection & control system shown above and understand how all of these components fit together to create a fully integrated system.
