to allow complete remote-plant supervision.

Medium and large power plants (hydro,

thermal, nuclear), as well as substations, are

controlled by sophisticated DCS’s whose

electrical input data (relevant to the different

systems composing the whole plant) can

be provided by Carlo Gavazzi power

quality analysers, such as the WM30,

WM40 or WM5, via the serial port by

using the Modbus RTU or TCP protocol, or

through an OPC server. If communication is

interrupted for any reason, the WM40 can,

if required, be equipped with a datalogger

module, allowing the system to recover

the missing information. The ﬂexible and

comprehensive ability of these instruments

them it into alarms or warnings - thanks

are implemented in our hardware. When

dealing with single distribution-gear,

control-gear or switch-gear (present not

only in generation facilities but also in

production sites and other infrastructures)

whereas in the past 3 analogue ammeters

and a voltmeter (whose input was selected

by a rotary switch) were used, the target is

to replace these with a single multifunction

meter or more high-performing digital

instrumentation. This results in the saving of

both space and money.
