Signal Description
Syst.is sym. Signal that the system state is symmetrical, i. e. the negative-sequence
current is below »I2 max«, and the positive-sequence current is above »I1
min«.
Blo dZ/dt Signal: The module has detected a system fault based on the »rate of
impedance change per time«, and therefore it has blocked itself.
Blo min.dwell time Signal: The module has detected a system fault based on the »minimum
dwell time«, and therefore it has blocked itself.
