New trip target timer
The new trip target timer can be configured to allow a second trip target on the
LCD. When several protection elements trip, the first trip target is displayed until
the time, as specified by the NEW TRIP IND. setting value, has expired. After this,
a new trip target can displace the old one. The basic protection functions are not
affected by the NEW TRIP IND. setting.
