Estandarización de ajustes, pruebas y programación de las funciones complementarias en relés numéricos de protección

Abstract

In the present work of certification, an analysis is made of the electronic relays of RED 670 of ABB, 7SA612 and 7SL87 of Siemens, P442 of Schneider, or P421 of SEL. The analysis encompasses its general characteristics, description of analog input / output module, and the communication software. The purpose of such analyses is to obtain and operate relay computer communications thus allowing access to the internal memory addresses & options. This allows access to the archived events, which are required to record results that are subject to either currents or test voltages.

The definitions and concepts of the functions sotf, recloser and fuse failures can be found on either manuals, catalogs, or qualification works. Such information is not generally found on your standard technical educational books since every manufacturer has their own implementations and use. This information is used to study the algorithms used by the RED 670 ABB, 7SA612 and 7SL87 Siemens numerical relays, P442 Schneider, and P421 SEL for the programming/ configuration of the functions mentioned above.
