Electrical Control & Protection Part 3

Electrical Control & Protection Part 3

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.

This course introduces electrical control & protection systems which are a critical part of any electrical network
