POWER QUALITY ANALYZER
SANDS Power Quality Analyzer PQ1108 is a wireless instrument with
the metrology in the base unit and all the HMI functions in the Android mobile or Tablet. All user
interfaces – textual and graphical are developed in the Tab, with a number
of innovative features. Also, field engineers can customize the screens to suit their requirements. With
the wireless communication between the metrology part – which is connected to the High Voltage - and the
user interface, human safety
is ensured.
Power Quality measurements can be carried out for both high
voltage and low voltage network using a variety of clamp Current Transformers (10A or 100A or 500A) or
flexible Rogowski current sensors (500A, 1000A or 3000A).
IS THERE A BETTER
ALTERNATIVE TO EXPENSIVE POWER QUALITY ANALYZERS?
“Harmonics always originate as
current harmonics, and voltage harmonics are the result of current harmonics.”
Current harmonics occur because of the presence of non-linear loads
like variable speed drives, inverters, UPS, television sets, PCs, semiconductor circuits, welding sets, and
arc
furnaces in the system. They act as harmonic current sources, thus,
in most applications, the first level diagnostics can be done well with current quality measurements and
analysis; a cost-effective alternative to expensive Power Quality Analyzers.
