HT PQA820 is a three-phase power quality analyzer and energy logger performing an easy and wide analysis of the most significant parameters of the electrical system. Thanks to an innovative project, the instrument can be interfaced to smart phones, tablets and PDAs (iOS and/or Android) meeting the requests of the most demanding professionals. All the electrical parameters can be displayed in both numerical and graphical mode, by waveforms, histograms and phasors. The vector diagram shows the phase angle between any voltage and the related current, revealing the inductive or capacitive nature of the loads connected.

The large built-in memory allows to log up to 383 parameters, granting a recording lasting more than one month with an integration period of 10 minutes.

HT PQA820 three-phase power quality analyzer records all parameters by default so avoiding any failure. The user will never miss recording the parameters he needs, since PQA820 records everything while selecting one of the three predefined settings (single phase, 3-phase without neutral, 3-phase with neutral).

PQA820 three-phase energy logger is powered by an internal rechargeable Li-Ion battery with a built-in user-selectable L-N or L-L power supply. The Wi-Fi and the USB interfaces grant  connection to smart phones, tablets, PDAs and PCs for instrument setting, recording start and stop, data downloading, and data analysis. Its IP65 waterproof hard carrying case allows PQA820 to work outdoors under critical environmental conditions









Artificial intelligence

You can analyze your data in two different ways Real Time and Recording mode
 

• Voltages,Currents and Powers and energy consumption analysis
• % THD, Cosphi and Power Factor
• Frequency
• Vector diagrams and waveforms
• Harmonics
• Voltage dips

Inflexible line against waste.

HT PQA820 can record for a long period all parameters as :

• Power Active, reactive and apparent
• Energy Active, reactive and apparent

And after you can compare them with:

• Cosphi and Power Factor
• Harmonics and THD%

With HTanalysis reduce waste will be a reality.



Zoom, Zoom, Zoom! Zoom in, jumps and analyze.

• ZOOM functions to view in detail all the variables recorded.
• HARMONICS JUMP function to see the harmonic content at any point in the recording by clicking.
• ENERGY JUMP function to see how much energy was consumed in every moment of the recording by clicking on the Power parameter.

HT PQA820 records of 383 default parameters simultaneously in systems PHASE 3 or 4 wires and Single Phase

• Voltages, Currents, Frequencies and Powers 
• % THD, Harmonics up to the 49th
• Cosphi, Power Factor
•  Voltage dips with 10ms resolution

Top Software

In the management of Power quality analyzers (PQA820 / PQA819) software allows the following operations:
 

• Creating a professional report
• 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 data from device to PC via USB / WiFi and accurate analysis of the data analysis programmed with the same views in both numerical / tabular both graphical
