Polar Star

MEASUREMENT

base/top

Panel mounted Power Quality analyzer

The high technological content, the great attention to the choice of materials, full compliance with industry regulations, make this instrument a reference (the “North Star”) to orient themselves with efficiency and simplicity in the control of electricity consumption and the main parameters power quality.

Polar Star was conceived, designed, built and tested entirely in Italy, and therefore manufactured with quality assurance that distinguishes European products, in the real environment and ethics.

His communication skills allow its use in Elcontrol monitoring networks of any size and geographical location. Two available versions 8Base and Top) allow to fit best any application requirement.

Field of use

Polar Star has a powerful engine of analysis and calculation that allows a wide range of sizes and capabilities:

Standard measures also according to IEC 61000-4-30 of V, I, P, Q, A, F, PF, THD%, instantaneous values / min / max / avg, absorbed and products, energy meters (kWh, KVA , kVAr) absorbed and generated;
Harmonic analysis of 7 channels (3 voltages and 4 currents) up to the 31st order, with its graphical and numeric display
Extent of outages and network brownouts
Extent of the DIP (voltage drops)
Extent of SWELL (Surge)
Graphical display of TREND (trends over time) of 6 selectable sizes
Measuring energy in 4 time periods (tariffs) set
Automatic connection test to determine if the connections of the voltages and currents are correct
Customization of the user display, which can independently choose which values to keep under control;
