Abstract
The analysis of the restricted earth fault differential protection based on the implementation of a low impedance scheme that allows the protection of 3.5 kVA generator windings using the overcurrent relay in differential structure is presented. The configuration and testing of the 7SJ85 overcurrent protection relay is mainly focused on the built-in ANSI 87N, REF protection function. The configuration, parameterization and operation of the elements that make up the protection system are performed using OMICRON's CMC 356 and the 7SJ85 relay with their respective application software Test Universe and Digsi 5. The values used for the tests are based on the short-circuit analysis applying the IEC 60909 standard and the Complete method (equivalent to Thevenin), which were calculated and simulated in MatLab and DigSilent software respectively.
