Parameters
It is possible to modify various parameters:
Parameter Description
Enable To activate/deactivate the protection.
Threshold Kq It defines the slope of the protection function.
Threshold Q24
It defines the starting point on the Q axis of the protection curve.
It is represented both as an absolute value (kVAR) and a relative value (Sn,
referring to the rated voltage set on the trip unit).
NOTES: the threshold expressed in Sn is preceded by the sign “- “ in
order to indicate that it refers to reverse power.
Time t24
This is the delay time between the exceeding of the tripping threshold and the
sending of the opening command
Threshold Vmin
It is the minimum voltage for activation of the protection. If a there is at least
one line-to-line voltage present below the Vmin threshold, the protection is not
active.
RQ protection has StartUp enable, see page 71.
Via Ekip Connect it is also possible to access the blocking functions, see page 72.

Function
OQ protection trips when the power supplied rises above the set threshold.
If the reactive power rises above the activation threshold, the protection trips within a fixed time set by the
user.
Parameters
It is possible to modify various parameters:
Parameter Description
Enable To activate/deactivate the protection.
Threshold Q27
It defines the reactive power value above which the protection is activated (with
reference to the figure above, the threshold is the part of the curve parallel to
the y-axis).
It is represented both as an absolute value (kVAR) and a relative value (Sn,
referring to the rated voltage set on the trip unit).
Time t27
The delay time between the exceeding of the Q27 threshold and the sending of
the opening command (with reference to the figure above, the threshold is the
part of the curve parallel to the x-axis).
OQ protection has StartUp enable, see page 71.
Via Ekip Connect it is also possible to access the blocking functions, see page 72.
