A shorter response time can set for changes that not have take the history the

1 Evaluating the absolute value and angle reveals that considerably more grid switches
were performed.
The circuit defined relative value the last saved zero sequence voltage.1.8) (Uref 1. the zero sequence voltage returns the tolerance range before the

Evaluation the absolute value the zero sequence voltage search process started

The factory setting reduce the waiting times during commissioning.
