Abstract
Switching of filter banks can have a severe impact on circuit breaker requirements and performances, due to the high harmonic content in the current to be interrupted and to the distortion of the transient recovery voltage. Attention must be paid to some particular operations which are likely to cause stresses exceeding the figures stated by present standards and have to be analyzed in detail. In some cases, these stresses could determine the number of breaking units of the circuit breaker better than other system requirements like rated short circuit breaking capability, short line fault, etc. The situation can also be more complicated if the circuit-breaker has to be subjected to stresses coming from conversion transformers and harmonic filters switching. The paper presents the results of extensive studies to establish the worst stresses applied to the circuit breaker for SACOI 2 HVDC link between Sardinia and mainland Italy through Corsica. Moreover, the testing activities carried out to verify the ability of the circuit-breaker to withstand the above mentioned stresses are also presented. The peculiarity of these stresses required the setting up of a suitable test circuit to verify the performance of the circuit breaker.
