Description
Electrical 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.
