Parameters
Parameter Description
Activates/deactivates the protection and its availability in the
Enable
parameters menu
Activates/deactivates transmission of the open command: if disabled,
Trip Enable the alarm and exceedance of protection time are only managed as
information
Defines the gradient of the line relating to threshold Q24.
Threshold Kq
The value is given as absolute value (slope of the line) and can be set
within the range: -2 to 2 in 0.01 steps
This is the reactive power required to define the trip line and relative
TRIP area.
Threshold The value is given as both absolute value (kVAR) and relative value (Sn)
-Q24
and can be set within the range: 0.1 Sn to 1 Sn in 0.001 Sn steps
NOTE: the threshold expressed in Sn is not preceded by the "-"
sign, but should still be understood as inverse reactive power
Defines the gradient of the line relating to threshold Q25.
Threshold
The value is given as absolute value (slope of the line) and can be set
Kq2
within the range: -2 to 2 in 0.01 steps
Defines the reactive power value at which the protection trips and is
required for the purpose of defining the relative TRIP area
Threshold The value is given as both absolute value (kVAR) and relative value (Sn)
-Q25 and can be set within the range: 0.1 Sn to 1 Sn in 0.001 Sn steps
NOTE: the threshold expressed in Sn is not preceded by the "-"
sign, but should still be understood as inverse reactive power
This is the trip time of the protection; the value is given in seconds
Time t24
and can be set within a range: 0.5 s to 100 s, in 0.1 s steps
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
Threshold
protection is not active.
Vmin
The value is given as both absolute value (V) and relative value (Un)
and can be set within the range: 0.5 Un to 1.2 Un in 0.01 Un steps
Limitations and additional functions
• Ekip Touch accepts parameters in accordance with the following limitations: Q24 < Q25 and Kq < Kq2
• 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).
Total cosφ is calculated as ratio between total active power and total apparent power.
Parameters
The parameters are available in the Advanced - Signaling menu (page 47)
