In particular it is possible to:
– send opening and closing commands to the
circuit-breakers
– read the electrical values of the installation (current,
voltage, power factor, etc.)
– read and modify the trip characteristics of the protection
unit
– determine the status of the apparatus (open, closed,
number of operations, trip for fault, etc.)
– determine abnormal operating situations (e.g. overload)
and, in the case of releases tripping, the type of fault
(short-circuit, ground fault, value of the interrupted
currents, etc.)
– log the history of the installation (energy consumed, most
highly loaded phase, any warnings of anomalies or faults,
etc.)
– illustrate evolution of the installation over time by means
of graphic diagrams.
Access to the various functions of the system can be ena-
bled by means of a password with different levels of au-
thorisation.
Putting the SD-View 2000 system into service is simple
and rapid: in fact, the software itself guides the user in rec-
ognition and configuration of the protection unit.
The user only needs to know the characteristics of the in-
stallation.
Operator use is extremely simple: the graphic pages of SD-
View 2000, based on Internet Explorer, make
management of the installation as simple as surfing
the Internet. The graphic pages relative to each
circuit-breaker are particularly intuitive and easy to use.
SD-View 2000 is the ideal tool available to managers in
order to have the situation of the plants under control at all
times and to be able to control all their functions simply
and immediately.
The operator station (personal computer) allows informa-
tion to be received from the installation and to control the
circuit-breakers and relative releases.
