WARNING! The Power flow parameters effect the sign of the power and power factor
values measured by the unit. Power flow must be configured and verified on the basis of
your installation to ensure that all the protections of the Power Protections package
function correctly
Function
The protection sends a TRIP command if the reverse total active power exceeds threshold P11 for longer
than t1.
t
To check and simulate the trip times in relation to all the parameters, please consult:
• summary table of the protections with the operating characteristics (page 96)
• the graph with trip curve (page 109)
Parameters

Parameter Description
Activates/deactivates the protection and its availability in the
Enable
parameters menu
Activates/deactivates transmission of the open command: if
Trip Enable disabled, the alarm and exceedance of protection time are only
managed as information
Establishes the value that activates the protection.
The value is given as both absolute value (kW) and relative value (Sn)
Threshold P11 and can be set within the range: -0.05 Sn to -1 Sn in 0.001 Sn steps
This is the trip time of the protection; the value is given in seconds
Time t11
and can be set within a range: 0.05 s to 120 s, in 0.01 s steps
Limitations and additional functions
The block functions can also be accessed by means of the service connector (via Ekip Connect) or by
connection to the system bus (page 86).
Type of protection
Reverse active power
Directional short-circuit with adjustable delay
Maximum reactive power
Active overpower
Active underpower
Reverse reactive power
Minimum cosφ
NOTE: the threshold expressed in Sn is preceded by the "-" sign
to indicate that inverse power is involved
