Standard verification campaigns IEC 61000-4-30 Definition of the measurement methods The International Electrotechnical Commission (IEC) has drawn up the IEC 61000-4-30 standard. This standard defines: • the methods for measuring the quality parameters for the supply of power to electrical power networks • in the form of alternating current at a stated fundamental frequency • and how to interpret the results. The measurement parameters are described for each applicable parameter in terms which provide reliable, repeatable results, however the method is implemented. EN 50160 Homogeneous tolerances...

The CA 8345: a diagnostic tool Viewing the signal and its components The CA 8345 is an easy-to-use analytical tool. After connection, the CA 8345 immediately and totally automatically displays the voltages up to 1,000 V AC and DC and the currents, thanks to a function which automatically recognizes the sensor connected. A large number of sensors are compatible with the Qualistar range. The Waveform mode automatically provides an oscillogram showing It is very simple to measure harmonics and interharmonics with the voltage and/or current waveforms. the CA 8345, which is very easy to use as an...

Standard verification campaigns Energy valuation The Qualistar Class A offers users all the measurements required to successfully implement energy efficiency projects and monitor electricity distribution. Shockwaves Usually caused by lightning, shockwaves are spectacular instantaneous electrical voltage surges. They also propagate in the digital network. The Qualistar Class A can withstand shockwaves up to 12 kV which are sampled every 500 ns. Carrier currents In the harmonic analysis function, there is also a mode for monitoring carrier currents. After defining their frequency in the instrument,...

Monitoring Trend The trend graph shows the variations of the parameters measured over time every 200ms. Alarms Alarms for parameterizing the threshold overruns to be monitored, which are then recorded and time-stamped with the duration and extreme values. Users can be informed directly by email when an alarm is triggered. Transients Transients correspond to peaks in the voltage or current waveform. Shockwaves are extremely fast transients with even greater possible amplitude TrueInrush For tests when starting up loads, these instruments can record ½-period values covering more than half an hour...

Communication Software The web server The Qualistar Class A models are equipped with firmware for remote access. It can be controlled via VNC. which controls a remote machine while displaying its desktop. It can be activated from any browser (Chrome, Edge, Firefox, Qwant, etc,). This means you can use any PC or smartphone, whether it is managed by iOS or Android. The Power Analyzer Transfer software processes the measurements made with the Qualistar Class A. • Configuration of the instrument: setup, recording, alarms • Real-time display • Processing of all the recorded data • Transfer of screenshots...

Applications Tertiary and industrial Today, electrical distribution networks are judged according to their ability to power loads causing disturbances and loads sensitive to disturbances. The latter may take multiple forms. A voltage quality analyser can be used to detect and qualify each one: outage, dip, voltage swell, flicker, THD, voltage variations, etc. Energy efficiency For energy diagnostics on a site, a logger must be set up to record the electrical power and energy consumed. Once all the measurements have been taken, the billing data are compared with the actual measurements. The study...
