Presentation
Two
Measurement
modules are available:
•
Measurement enabler
installed by default on Ekip Touch and enabled in the presence of the
Measuring Measurements package (enabling can be obtained both at the time the circuit-breaker
is ordered or at a later date, via Market Place)
•
Measurement enabler with voltage socket
is installed by default on Ekip Hi-Touch, Ekip G Touch
and Ekip G Hi-Touch; can be installed in conjunction with Ekip Touch if requested when circuit-
breaker is ordered
Both modules measure voltages, frequencies, power and energy values; in addition, the
Measurement
enabler with voltage socket
module allows:
• the Trip unit to be supplied directly by the voltage sockets to which it is connected
• management of the synchronism function when the
Ekip Synchrocheck
module is installed (see
chapter dedicated to
Ekip Synchrocheck
from page 247).
Measurement performance
The measurement performance provided when the
Measurement
modules are installed (described on
page 117), are more accurate when the
Class 1 Power & Energy Metering
package is present (described on
page 120.
Configurations available
Both modules can be ordered with different connection configurations:
• connections to internal terminals or in an external terminal box
• connections to the upper or lower terminals of the poles on the basis of the expected power flow
• with normal or reverse pole order
For full details about ordering and the connections, consult technical catalog 1SDC200023D0906 and the
wiring diagrams 1SDM000091r0001.
Electrical characteristics
The
Measurement
modules function correctly in the electrical conditions described on page 20.
Installations with up to 1200 VAC line-to-line voltage can be connected and configured in the presence of
connections to external sockets and an isolation transformer.
Isolation transformer
The isolation transformer must conform to standard IEC 60255-27 and possess the following
characteristics:
Characteristics Description

• Performance: ≥ 10 VA
• Overload: 20 % permanent
• Insulations: 4 kV between inputs and outputs, 4 kV between shield and
outputs, 4 kV between shield and inputs
• Frequency: Fn +-10%
• Primary voltage: 100 to 1200 V (nominal, to be configured via menu)
• Secondary voltage: 100 to 230 V (nominal, to be configured via menu)
