Resumen
The Tecnológico de Costa Rica has been experiencing big changes in structural level
in recent years; those changes are from new buildings until remodeling of their
existing structures.
The necessity of the Office of Engineering and Maintenance Management
Department is when those changes were done, the majority of the information of their
buildings had been altered without be updated.
The problem of not having this information updated, it’s about futures jobs in
electronic level because could have confusion and inconsistencies that could delay
the labor of the technicians and of designs of the engineers.
This project has as main objective to update line diagrams, because we don’t have
this information so far, make an analysis of short circuit currents to ensure that before
an event all of the short circuit currents will be capable to supporting this
phenomenon clearing satisfactorily and isolating the equipment to avoid being
affected. And finally to check the status of coordination of protections of the buildings
A, B, C and D of the supply connection and the main central offices of Tecnológico de
Costa Rica.
The analysis of the short circuit currents will be based in the next norms
IEEE_0141_1993 (Red) Electric Power Distribution for Industrial y IEEE_0551-2006
(Violet) Calculating short circuit currents in Industrial and Commercial Power
Systems.
The calculation methodology, which is basing by means of the consulted standards,
will be validated by means of simulation software SKM of power tools with the final
purpose to compare results.
