Online Circuit Breaker Monitoring System. (December 2007) Zarko Djekic, B.S., University of Novi Sad, Serbia Chair of Advisory Committee: Dr. Mladen Kezunovic Circuit breakers are used in a power system to break or make current flow through power system apparatus. Reliable operation of circuit breakers is very important to the well-being of the power system. Historically this is achieved by reg...
In medium voltage vacuum circuit breakers, in order to achieve an even distribution of force along the entire length drive shaft, mechanism is made per phase, that is, a separate electromagnet installed under each pole. The analysis designs and features operation breakers with phase electromagnetic carried out. Deficiencies these drives have been identified. design breaker kinematic diagram mon...
