The following is required from a circuit breaker: In the closed position it must be a good conductor; In the open position it must behave as a good isolator between system parts; It must be able to change from the closed to open position in a very short period of time (typically in less than 0.1 second);
This chapter traces the evolution of standards for alternating current high-voltage circuit breakers in the IEEE, formerly AIEE, from approximately 1900 to 2007.
High voltage circuit breaker design and operation as well as type and routine tests are deined by international standards such as: ieC 62271-ser ed1.0 - High-voltage switchgear and controlgear. ansi/ieee C37 - guides and standards for Circuit Breakers, switchgear, relays, substations, and Fuses.
Chapter (2) Circuit Breakers 2.1 Introduction A circuit breaker is required to perform the following three duties: 1. It must be capable of opening the faulty circuit and breaking the fault current. 2. It must be capable of being closed on to a fault 3. Must be capable of carrying fault current for a short time while another breaker is clearing
