The personal computer offers several advantages over both manual methods and shared-computer methods for overcurrent protective device coordination. The fast graphics display of a personal computer makes it possible to achieve a practical replacement for the light table. A computerized approach to overcurrent protective device coordination is presented. A flexible, hierarchical database permits convenient storage and retrieval of any time-current-characteristic curve. An expert system is implemented through a macro language, built around simple functions. The design choices for the personal computer program are discussed and an implementation meeting the design requirements is presented.>
