Ekip Measuring - ABB SACE Tmax XT5 Operation And Maintenance Manual

2 - Ekip Measuring

Presentation Ekip Measuring allows the following measurements to be taken:
Electrical characteristics Ekip Measuring functions correctly in the following conditions:
Connection configurations The module is connected directly to the internal sockets of the CB.

• Voltage (RMS measurement of line-to-line voltages and phase voltages in the applicable cases)
• Frequency of the voltages
• Power and energy, also using the phase current measurements
Measurement performance is higher if the Class 1 Power & Energy Metering package is present.
NOTE: measurement performance is described on page 101 and 104.
If used in conjunction with Ekip Synchrocheck, recognition of whether the synchronism conditions between
internal sockets and external contacts are able to allow the synchronism contact to close can also be obtained
(see chapter dedicated to Ekip Synchrocheck from page 164).
Component
Phase-to-phase input voltage
Input frequency
In the 3P + N configuration, the external neutral voltage (V0) can be connected to the trip unit so as to
measure and protect the residual voltage. Consult circuit diagrams 1SDM000005A1001.
Menu The specific configuration area will activate in the Settings-Modules menu if the Ekip Measuring module is
detected correctly by Ekip Touch..
The following parameters can be configured in this menu:
Parameter
Rated voltage
Positive Power flow
Neutral connection
About The About-Modules menu contains the specific menu of the module with the serial number and version of
the module itself.
Test The dielectric test is described in the Installation instructions 1SDH002011Ar0001, 1SDH002011Ar0002.
Description
Available in the absence of a transformer; defines rated voltage
Un.
The value is given as absolute value (Volts) and can be set
within the range: 100 V to 690 V with variable steps.
Defines the power flow required for D protection; there are 2
options available (page 61):
• High → Low: the power flows from the low terminals to the
high ones (load connected low)
• Low → High: opposite power flow (load connected high)
Available with 3P CB; allows the presence of the external
Neutral to be enabled.
NOTE: presence of the neutral activates phase voltage
