Using the SIL concept, three 500 kV or six 345 kV circuits would be required to achieve the loadability of a single 765 kV line. Specifically, a 765 kV line can reliably transmit 2200-2400 MW (i.e., 1.0 SIL) for

library.e.abb.comProtection against short-circuits Figure 1 shows typical let-through or I2t values of overcurrent circuit-breakers. In the case of S201-B16 miniature circuit-breaker, this causes the let-through energy to be limited to approx. 20,000 A2s if a prospective short-circuit current i K = 6 kA occurs. This value is far less than 29,700 A2, meaning
