A low voltage electrical installation is similar to an industrial process for electricity distribution
and needs a supervisory and monitoring system that is able to increase reliability and optimize
management.
To achieve integration between conventional plant engineering techniques and control sys-
tems for the purpose of running, controlling and monitoring civil and industrial installations in a
centralized and automatic way, one can consider the electrical installation as being affected by
two flows:
n
a main flow (energy flow) formed by the power and energy supplied to the users and loads
of an installation through the line conductors and control and protection devices;
n
an information flow (digital flow) formed by all the information, data and commands required
to control and manage the installation.
The supervisory system handles the flow of information that transits through the communica-
tion network.
In this type of installation, the circuit-breaker acts as both sensor and actuator. As a sensor,
it collects sensitive information and data and sends them to the supervision system. As an
actuator, it executes the command received from the control device (e.g. PC or PLC).
These characteristics are of particular importance since they meet the growing demands for
circuit-breaker integration into latest generation networks (Smart Grid).
