A Protections | 5 - Power protections5 - Power protectionsElenco The Power protections, available by default for the Ekip Hi-Touch, Ekip G Touch, Ekip G-Hi Touch and Ekip MTouch models and configurable in the remaining models as additional SW package, are:Name Type of protection PageRP Reverse active power 60D (2) Directional short-circuit with adjustable delay 63OQ (1) Maximum reactive power 63OP (1) Maximum active power 63UP (1) Minimum active power 64RQ (1)(2) Reverse reactive power 64Cos φ Minimum Cos φ 65(1) protection not available by default with Ekip Hi-Touch and Ekip M Touch. However, it can be integrated byrequesting the relative SW package(2) protection not available by default with Ekip G Touch. However, it can be integrated by requesting the relativeSW packageRP ProtectionP11tt11PRPFunctionThe protection sends a TRIP command if the reverse total active power exceeds threshold P11 for longerthan 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 80)• the graph with trip curve (page 92)ParametersParameter Description DefaultEnable Activates/deactivates the protection and its availability in the parametersmenu OFFTrip EnableActivates/deactivates transmission of the open command: if disabled,the alarm and exceedance of protection time are only managed asinformationOFFThreshold f11Establishes the value that activates the protection.The value is given as both absolute value (kW) and relative value (Sn) andcan be set within the range: -0.05 Sn to -1 Sn in 0.001 Sn stepsNOTE: the threshold expressed in Sn is preceded by the “-” sign toindicate that inverse power is involved0,1 SnTime t11 This is the trip time of the protection; the value is given in seconds andcan be set within a range: 0.05 s to 120 s, in 0.01 s steps 10 sLimitations and additional functionsThe block functions can also be accessed by means of the service connector (via Ekip Connect) or byconnection to the system bus (page 75).
