The variations of short-circuit capacities (SCC’s) along a feeder while a primary network is upgraded from original radial to normally closed loop arrangement is essential for examining the protection system of the network after upgraded. The increments of SCC’s along a feeder may cause the existing protection devices installed at the original network and its customers’ distribution systems becoming...
The calculations of the short-circuit capacities (SCC's) along a primary feeder is essential for determining the ratings of protective devices of the distribution systems, especially in the planning stage. According to the calculation results, the interruption capacities (ICs) that shall be able to withstand the mechanical and thermal stresses resulting from maximum flow of short-circuit current through...
