Q
OQ
Function
The protection sends a TRIP command if one or more of the reactive power values detected by the unit
exceed threshold Q27 for longer than t27.
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 110)
Parameters
Parameter Description Default
Enable
Activates/deactivates the protection and its availability in the
parameters menu
OFF
Trip Enable
Activates/deactivates transmission of the open command: if
disabled, the alarm and exceedance of protection time are only
managed as information
OFF
Threshold Q27
Establishes the value that activates the protection.
The value is given as both absolute value (kVAR) and relative value
(Sn) and can be set within the range: 0.4 Sn to 2 Sn in 0.001 Sn
steps
1 Sn
Time t27
This is the trip time of the protection; the value is given in
seconds and can be set within a range: 0.5 s to 100 s, in 0.5 s
steps
1 s
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).
