circuit component connectivity evaluation and validation method provides comparing and validating the correctness of electrical phase connectivity at connection nodes between conducting components within a circuit model of a power distribution network or other circuit . phase connectivity requirements of each connected component / device / equipment in a particular circuit are obtained from a common interface model file containing parameter data describing the circuit . xml data strings obtained from the cim file are parsed into enumerated data objects representing each component &# 39 ; s phase connectivity requirements and assigned unique four bit binary phase connectivity mask values indicative of the particular electrical phase connectivity requirements of each component . associated mask values corresponding to connection nodes between pairs of connected components are bit - wise logically “ and ” ed and the result compared to each component &# 39 ; s bit mask to validate that each connected component in the circuit is a correct phase type match with other components to which it is connected .
