To one double-breaker model, experimental investigation on blow open force was carried out. It demonstrates that the ratio between the emerging blow open force and arc power FB/ui decreases with the arcing time, the contact gap has less effect on FB/ui, and the characteristics of the blow open force are similar when the peak value of the short circuit current is beyond 4 kA. Then, according to ...
-This paper examines the impact of the network modification produced by the replacement of an existing conventional generator with a high voltage directly connected generator on the adequacy of existing circuit breakers distributed throughout a high voltage transmission network. The significance of generator design changes is assessed by comparing the critical fault types producing maximal circ...
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...
-With the connections between the safe operation and national economy development getting closer, the original scheduled maintenance has been unable to adapt to the current demand for electricity. The condition-based maintenance, which is an immediate and effective maintenance mode for supply equipment, achieves supply companies general concern. This paper aims at the existing problems in on-po...
