A network intelligent protective device coordination program for transmission and distribution-systems relays, fuses, magnetic and solid-state circuit breakers, MCPs, etc

Some of the general techniques and calculating methods used in some of the EDSA programs are presented. The program discussed is protective device coordination. The protective device coordination program may be used to select devices which achieve a selective and sensitive protection system. The program searches a database of devices of various major manufacturers and, in turn, generates an optimum choice of devices.<>
