DescriptionElectrical control & protection systems are a critical part of the distribution & transmission systems that feed power to our cities & industries.
The third part of this protection course focuses on protection systems for low voltage & distribution networks and busbar protection
The course will go into detail for the following key topics :-
- Introduce the general principles behind differential protection.
- Show how we use current transformers to form protection zones for various common substation configurations
- Show how to use logarithmic graphs for time current grading
- Look at the time current characteristics for fuses, MCB’s & circuit breakers
- Show how we use damage curves for busbars & cables
- Introduce the principles of protection grading and show how we use time current characteristics to discrimate for overloads and fault situations
- Look in detail at RMU protection
- Introduce the design features of Metalclad switchgear & their protection equipments
- Show how we size busbars
- Provide a simple methodology for calculating the fault current for transformers
- Show how we provide simple busbar protection systems for distribution networks
- Look in detail at high impedance differential busbar protection
By the end of the course the student will be able to identify all of the key components of a protection & control system and understand how all of these components fit together to create a fully integrated system.
