(Non Directional & Directional) Overcurrent - Restricted Earth Fault
Power transformer protection systems are a critical part of the distribution & transmission systems that feed power to our cities & industries.
The aim of this course is to introduce all of the basic principles associated with these complex systems.
The course will go into detail for the following key topics :-
Show the basic principles behind electrical protection philosophy
An introduction to How the omicron cmc 356 device works
Look at three phase currents and see how they can be broken down into sequence components and harmonics.
Working theory of non directional overcurrent
How test overcurrent curves by using advanced module of omicron device ?
How test overcurrent by using any 3 Phase injection device and how can write accepted report ?
Provide the basic principles behind current transformers, how they operate and need to be connected
Working theory of directional overcurrent
How test directional overcurrent by using advanced module of omicron device ?
How Test Directional overcurrent by using any 3 phase injection device and how can write accepted report ?
Working theory of restricted earth fault
What the different between high impedance and low impedance restricted earth fault ?
How test restricted earth fault relay ?
Can the CMC 356 device or any 3 phase injection device test high impedance restricted earth fault relay ?
By the end of the course the student will be able to test(non directional & directional) overcurrent - restricted earth fault relays by using any 3 Phase Injection Device and by using advanced module of omicron device
