|NEW HYBRID CURRENT LIMITING DEVICES|
The problem of effective current limiting under severe fault conditions can not be solved by means of conventional circuit breaker or even fuses. They are relatively slow acting circuit breakers with low short circuit current limiting ability. A new approach are a hybrid circuit breakers (HCB). The new actually available solutions of the HCBs are discussed. They were classified into three classes depending on the current limiting principles. Future development trends in the field of HCBs were discussed shortly.
