Presentation
Ekip Measuring
allows the following measurements to be taken:
• 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
and
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
Electrical characteristics
Ekip Measuring
functions correctly in the following conditions:
Component
Range
Phase-to-phase input voltage
0 ÷ 760 VAC (692 VAC + 10 %)
Input frequency
30 ÷ 80 Hz
Connection configurations
The module is connected directly to the internal sockets of the CB.
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
.
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
Description
Default
Rated voltage
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.
400 V
Positive Power flow
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)
High
→
Low
Neutral connection
Available with 3P CB; allows the presence of the external
Neutral to be enabled.
NOTE
:
presence of the neutral activates phase voltage
measurement
Absent
