SIPROTEC 7SJ80

    The 7SJ80 features “flexible protection functions”. 20 additional protection functions can be created by the user. For example, a rate of change of frequency function or a reverse power function can be created.

    The relay provides circuit-breaker control, additional switching devices can also be controlled from the relay. Automation or PLC logic functionality is also implemented in the relay. The integrated programmable logic (CFC) allows the user to add own functions, e.g. for the automation of switchgear (interlocking). The user is also allowed to generate user-defined messages.
