7.3. Connecting to the electrical network and loads
DIRIS Digiware can be used on single-phase, two-phase or three-phase networks.
Each DIRIS Digiware I and S current measurement module can simultaneously measure several loads, for example
a three-phase load and a single-phase load. This approach allows great flexibility in terms of where it is fitted in the
installation.
The loads are measured using several types of current sensors (solid-core, split-core, flexible) selected depending on the
new, existing or high-current installations. The link between each DIRIS Digiware I current measurement module and its
associated sensors is made using specific cables. With this connection you can quickly and easily install the units without
any risk of cabling error and in complete safety. The connected sensors are automatically detected.
In addition, DIRIS Digiware can identify the majority of load types to be measured: single-phase, three-phase with or
without neutral using 1, 2, 3 or 4 sensors for balanced or unbalanced loads.
The overall accuracy of the measurement chain (DIRIS Di sensors) is guaranteed. To guarantee this accuracy,
SOCOMEC current sensor connection cables or equivalent must be used.
