Function
OF protection trips when the line frequency rises above the set threshold.
If the line frequency rises above the activation threshold, the protection trips within a fixed time set by the
user.
NOTE:
the protection is not active for voltages <30V.
Parameters
Here is a list of the available parameters:
Parameter
Description
Enable
To activate/deactivate the protection.
Threshold f13
It defines the frequency 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 (Hertz) and a relative value (fn,
nominal value defined on the trip unit).
Time t13
The delay time between the exceeding of the f13 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).

Function
RP protection trips when the total reverse active power exceeds the reverse active power threshold set.
When the total reverse active power rises above the set threshold, the protection delays for the set time t11
and then opens.
Parameters
Here is a list of the available parameters:
Parameter
Description
Enable
To activate/deactivate the protection.
Threshold P11
It defines the power value for 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 (KW) and a relative value (Sn,
referring to the rated voltage set on the trip unit).
NOTE:
the threshold expressed in Sn is preceded by the sign “- “ in
order to indicate that it refers to reverse power.
Time t11
The delay time between the exceeding of the p11 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).
RP protection has

Via Ekip Connect it is also possible to access the
