Revision history [back]

How we get line constants for studies - written from the perspective of a high level system planner.

Stage one - Planning data When the initial plans are proposed by the system architects, we look at the voltage level of the line and other similar lines in the area to get a default line constants for use in planning studies.

Stage two - design data Consultants will run detailed studies and speak with contract firms that could build this project to project detailed line constants that will be fed back into our system model.

Stage three - as built data Having purchased the conductors and other equipment and with it installed, the as-built line constants are again fed into our system model for future record and later studies.
