VEGA78 is a Three-Phase and Single-Phase power quality and energy analyzer.
It allows the analysis of all electric parameters which can be measured nowadays, elaborating them easily and quickly.
This device can be easily programmed thanks to the new colour touchscreen display with icon menu style, which guarantees the selection of internal parameters in a simple and intuitive way.

Each internal parameter is easily reached through the typical tree structure, widely known to Windows system users. The device allows displaying the parameters in numerical and graphic mode, both for periodical analysis and for harmonic analysis. The graphic function “vector diagram” allows, among other things, to immediately evaluate the phase angle between input voltage and current signals, thus defining the loads’ nature. The 15MB internal memory allows saving recorded data for a remarkable number of consecutive days.
VEGA78, compared to PQA820 allows current measurement up to 3000A and voltage up to 1000V. The Help online function available on each screen is a valid and concrete help for the operator in understanding how the devices are used.
