List
The Power protections, available by default for Ekip Hi-Touch, Ekip G Touch, Ekip G-Hi Touch models and configurable in Ekip Touch as additional
SW package, are:
Name Type of protection Threshold Time Additional functions
(3)
RP Reverse active power Trip enable, Block
D
(2)
Directional short-circuit with adjustable delay
Trip enable, Directional Zone Selectivity
(4)
,
Startup enable, Block, Direction Min Angle
OQ
(1)
Maximum reactive power Trip enable, Block
OP
(1)
Active overpower Trip enable, Block
UP
(1)
Active underpower Trip enable, Block, Startup enable
RQ
(1)(2)

Further details about the protections are given in document 1SDH001330R1002.
(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
(3)
Block configuration available via Ekip Connect
(4)
Directional Zone Selectivity functions as an alternative to Zone Selectivity S and G
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
