Fig. 3-108: Phase current stages, internal overcurrent startings.
The three phase currents are monitored by the P634 with three-stage functions
to detect when they exceed the set thresholds. One of two different threshold
types can be active. The “dynamic” thresholds are active for the set hold time for
the “dynamic parameters” (see Section 3.12.8, (p. 3-88)) and the “normal”
thresholds are active when no hold time is running.
There is also a separate setting for each overcurrent stage whether the starting
decision shall be based on the fundamental or on the r.m.s. value.
