Circuit Breakers Maintenance

 

Course Introduction:

 

Electric Power Systems are designed to serve loads in a safe and reliable manner. One of the major considerations in the design of any power network is adequate control of short-circuits or “faults” as they are generally referred to. If faults are not controlled they can cause unnecessary loss of electricity service with all of its many ramifications.

 

Electric Power Systems are designed to be as fault free as possible through appropriate network design, equipment design, proper installation and on-going maintenance. The Circuit breaker and its associated fault detection equipment, protective relaying, is an extremely important device, through its role of clearing short-circuit currents, disconnecting faulty elements from the power network, and thus maintaining the overall integrity of the power network.
