HT ITALIA VEGA 78 Power quality analyzer

Thanks to an innovative development, the instrument VEGA78 power quality analyzer and energy logger allow carrying out analysis and tests on single-phase and  three-phase electric systems with and without neutral. The instrument display in real time the values of all fundamental electric quantities which characterize the electric system being tested (voltage, current, active power, reactive power, apparent power, power factor, etc.), showing the waveforms of voltages and currents. VEGA78 is used for testing and analysing the quality of the electric service provided by the Electric Power Supplier, for analysing single-phase and three-phase electric users such as offices and industries, when diagnosing voltage anomalies by taking advantage of the possibility of recording electric quantities. The instrument also allows evaluating the harmonic content introduced by non-linear loads such as computers, TV sets, controlled electric motors, etc. which can cause the RCD’s tripping or a neutral overheating. The instrument are supplied with the PC management software, which further expands the analysis possibilities of the data acquired.

In the management of Pqa analyzers (PQA82x / VEGA78) software allows the following operations: √ Creating a professional report on the quality of electricity service (according to EN50160)


√ Analysis of energy consumption for different time slot


√ Creating custom printing reports can also be exported in XLS and PDF.


√ Set the instrument (type of system, recording parameters, etc …)


√ Online display of measured by the instrument (numerical values​​, waveforms, histograms, sampling instant saving)


√ Start / Stop recording


√ Transfer the data from the instrument to the PC via USB and accurate analysis of the data analysis programmed on the same views on whether numerical / tabular both graphical.
