MULTIVOIES’s patent is based on the fact that Voltages are identical on every breaker in one switchboard. Thus, based on a unique Voltage (single or three-phase) probe acting also as system power supply, MULTIVOIES’s concentrator transfers in real time Voltage information in numerical format to all of the current modules. During set up, the user checks and sets the correct phase for each sensor, so that power and energy samples can be correctly computed (V x I).
Computations and data storage are carried out in each current module, in order to ensure the same storage capacity whatever the number of current modules used.
MULTIVOIES’s electrical safety is reinforced by the fact that dangerous voltages cannot be transmitted by the concentrator in the communication bus to the current modules and that all user interfaces are wireless.
Current and communication modules can be added on the communication bus up to a bus length of 10 meters. Thus, with 20 current modules and only one concentrator, you end up measuring 120 channels in the same switchboard.

Micrologger Systems: Microloggers are complementary to MULTIVOIES to store data with fully stand alone and low cost devices. They are packed in a very small housing with no screen, no button and communicate with a PDA using infrared beam. The technical specifications of the sensors are identical to those from the wireless sensors (see table above).
