The SIPROTEC 7SK80 features “flexible protection functions”. Up to 20 additional protection functions can be created by the user.
Therefore protection of change for frequency or reverse power protection can be realized, for example.
The relay provides circuit-breaker control, further switching devices and automation functions. 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.
