System Protection - The Art of Engineering Relays, Breakers, Reclosers & Fuses
In System Protection, you'll learn ...
- How to provide proper protection for electrical systems
- The differences between breakers, reclosers & fuses
- Common relay types and communication methods
- The consequences of improper circuit protection
Overview
System protection is known as the art of engineering, the building block of every utility. We need proper protection for generation, transmission, distribution systems and renewables: first and second line of defense as well as back-up protection.
Relays represent the brain power that differentiate between normal and fault conditions and trigger the operating muscle, which are the disconnecting devices, such as circuit breakers and reclosers to isolate the faults.
There are key differences between breakers, reclosers & fuses. The consequences for improper protection and/or relay mis-operation are grave.
This course will show the differences between breakers, reclosers & fuses, as well as the consequences of improper protection and/or relay mis-operation. This course will also cover special relay traits, protection zones, common relay types and communication methods, fuse curves and DER impact.
