(1)
the protection is not available by default with Ekip Hi-Touch. However, it can be integrated by
requesting the relative SW package
(2)
the protection is not available by default with Ekip G Touch. However, it can be integrated by
requesting the relative SW package
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
RP Protection
Function
The protection sends a TRIP command if the reverse total active power exceeds threshold P11 for longer
than t1.
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 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 P11
Establishes the value that activates the protection.
The value is given as both absolute value (kW) and relative value (Sn)
and can be set within the range: -0.05 Sn to -1 Sn in 0.001 Sn steps
NOTE: the threshold expressed in Sn is preceded by the “-” sign
to indicate that inverse power is involved
-0,1 Sn
Time t11
This is the trip time of the protection; the value is given in seconds
and can be set within a range: 0.05 s to 120 s, in 0.01 s steps
10 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).
