Computer-aided coordination and overcurrent protection for distribution systems

Conference ·
OSTI ID:397866
Overcurrent protection and coordination studies for electrical distribution systems have become much easier to perform with the emergence of several commercially available software programs that run on a personal computer. These programs have built-in libraries of protective device time-current curves, damage curves for cable and transformers, and motor starting curves, thereby facilitating the design of a selectively coordinated protection system which is also well protected. Additionally, design time when utilizing computers is far less than the previous method of tracing manufacturers` curves on transparent paper. Basic protection and coordination principles are presented in this paper along with several helpful suggestions for designing electrical protection systems. A step-by-step methodology is presented to illustrate the design concepts when using software for selecting and coordinating the protective devices in distribution systems.
