Análisis de protección diferencial para la detección de fallas a tierra en el estator de generadores

Abstract

Theoretical bases of faults restricted to earth are presented that allow establishing a scheme to protect the stator windings of the 3.5 kVA generator using overcurrent relay in differential structure. The configuration, parameterization and operation are carried out using the OMICRON CMC 356 and 7SJ85 protection relay with their respective Digsi 5 and Test Universe application software.
