VEGA78 Power Quality and Energy Analyzer


The VEGA78 is a Single-Phase and Three-Phase Energy Consumption and Power Quality analyzer.

To illustrate, the VEGA78 Power Quality Analyzer let you carry out the analysis of all electric parameters; and also allow you to elaborate them quickly and easily.

Thanks to the new color touchscreen display with icon menu style; the VEGA78 meter can be easily programmed. In other words it ensures the selection of internal parameters in an intuitive and simple way.

Moreover, using the Windows system user which is widely known as typical tree structure, each internal parameter is easily reached.

Also, the VEGA78 Analyser allows displaying the parameters in graphic and numerical mode; both for harmonic and periodical analysis.

Besides, the graphic function “vector diagram” let you evaluate the phase angle between current signals and input voltage immediately; which leads to defining the loads’ nature.

Equally important, the 15 MB internal memory of the VEGA78 Analyzer allows saving of recorded data for a large number of consecutive days.

Furthermore, the HT Instruments VEGA78 Power Quality and Energy Analyzer offers a wide variety of features.
