Electrical Power & Protection


Power analysis and energy saving evolved

June 2019 Electrical Power & Protection

Advanced power and energy consumption analysis is now available using a smartphone or tablet. The TPQA820 is a true RMS, self-powered 3-phase power quality analyser used to analyse and record the most significant parameters of electrical systems. All parameters required are recorded simultaneously, which ensures potential failures are avoided with the built-in 8 MB memory allowing the instrument to log up to 383 parameters, with recordings lasting more than one month with an integration period of 10 minutes.

Through the free-to-download analysis app it is possible to interface wirelessly with the TPQA820 to display recordings of voltage, current, power, harmonics, THD%, cosphi and frequency. The electrical parameters are displayed instantly in both numerical and graphical mode, by way of 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 analyser enables users to store all recordings into the cloud database and share them through mail as well. The instrument is powered by an internal rechargeable lithium-ion battery and has a built-in user selectable L-N or L-L power supply. It can interface to smartphones, tablets and PCs via the WiFi or USB connections. The IP65 waterproof hard carry case allows work outdoors under extreme environmental conditions. In addition there are CATIV 300 V (ground) and CATIII 415 V (between inputs) safety ratings. Additional feature include:

• DC and AC active, reactive, apparent power.

• Voltage anomalies (sag, swell) with 10 ms resolution.

• Voltage unbalance.

• LED indication of phase sequence.

• Frequency.

• Parameter data table, graphs, harmonic histograms, voltage and current phasors with PC or mobile device connection.
