HT-INSTRUMENTS VEGA 78 PROFESSIONAL POWER QUALITY ANALYZER • TRMS P-N, P-P, P-PE voltage measures (5 inputs) • TRMS current on phases and neutral (4inputs) • Active, reactive and apparent powers measures • Active, reactive and apparent energies measures • Power factors measure • Frequency measure • Max 251 selected parameters at the same time • Integrated period selectable from 1s to 60min • Harmonic analysis of voltage and current up to 49th component • Voltage anomalies (sags, swells) with 10ms resolution • Numerical and graphical (waveforms) visualization • Histogram visualization of harmonic analysis • Vectorial diagram of voltages and currents • Voltage unbalance • Predefined recordings of parameters • TFT colour display with "touch screen" • 15Mbytes internal memory for recordings saving • Using of external compact flash and USB pen drives • USB interface for PC connection • Windows software for recordings analysis • Rechargeable Li-Ion battery and external AC/D adapter • Contextual help selectable on each screen • Virtual keyboard at display Thanks to an innovative development, the instrument VEGA78 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.
