Power Quality
The
nature of our voltage mains has changed greatly in the last
10 years. With the proliferation of non-linear loads such as
inverters, power converters, switch-mode power supplies, and
computers, there is a growing concern for the quality of our
power sources.
Problems
often arise which can cause equipment failure or shut-down
resulting in significant costs and loss
of production. Power quality problems can result
in failure of compensation capacitors, tripping of fuses, over-heating of
transformers and motors, failures of electronic equipment,
and high neutral currents. Carlo
Gavazzi offers a broad range of power quality meters and transducers
which give early warning of power quality problems - allowing
preventative action to be taken before a major failure results.
Most of our products offer relay outputs that can be used to
immediately shut down a piece of equipment if a certain threshold
is reached. Another option is to connect to your PLC or PC
control system to provide plant wide monitoring of power quality
using 4-20 mA current signals or via RS485 communications.
Carlo
Gavazzi also offer a number of software products for monitoring
of a network of meters and transducers. This allows at-a-glance
viewing of your complete power system
