Power Protections - ABB SACE Emax 2 Instructions Manual

6 - Power protections

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
RP Reverse active power
D (2) Directional short-circuit with adjustable delay
OQ Maximum reactive power
(1)
OP Active overpower
(1)
UP Active underpower
(1)
RQ (1)(2) Reverse reactive power
CosΦ Minimum cosφ
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
the protection is not available by default with Ekip G Touch. However, it can be integrated by requesting the relative SW package
(2)
Block configuration available via Ekip Connect
(3)
(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
