Electricalcontrol & 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 networksand busbar protectionThe course will go into detail for the following key topics :-Introduce the generalprinciples behind differential protection.Show how we use current transformers to form protection zones for various commonsubstation configurationsShow how to use logarithmic graphs for time current gradingLook at the time current characteristics for fuses, MCBs & circuit breakersShow how we use damage curves for busbars & cablesIntroduce the principles of protection grading and show how we use time current characteristicsto discrimate for overloads and fault situationsLook in detail at RMU protectionIntroduce the design features of Metalclad switchgear & their protection equipmentsShow how we size busbarsProvide a simple methodology for calculating the fault current for transformersShow how we provide simple busbar protection systems for distribution networksLook in detail at high impedance differential busbar protectionBy theend of the course the studentwill 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.
