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 that provide reliable, repeatable results, however, the method is implemented.

IEC 61000-4-7
Harmonics and interharmonics
The IEC 61000-4-7 standard defines the measurement methods for voltage quality analyzers so that they remain compliant with the emission levels stipulated in certain standards (e.g. the harmonic current limits specified by IEC 61000-3-2) and for the measurement of harmonic currents and voltages on the power networks themselves.

---|---

Homogeneous tolerances
The EN 50160 standard characterizes the quality of the voltage supplied. It presents the different types of disturbances that may affect the voltage on a network. It lists the parameters to be monitored and defines how long the parameters should be monitored.
With the PAT3 software, the Monitoring mode can be used to set up a simplified configuration of all the limits to be monitored and the parameters to be recorded.

IEC 61000-4-15
Short or long-term flicker
This is caused by mains voltage modulation. When it affects lighting, it gives an impression of unstable vision due to a light stimulus whose luminance or spectral distribution fluctuates over time.
There are 2 parameters calculated from the mains voltage.

• Pst which is a short-term assessment based on a 10-minute observation period
• Plt which is a long-term assessment, usually over a period of 2 hours

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 that automatically recognizes the sensor connected.
A large number of sensors are compatible with the Qualistar range.

|
---|---
The Waveform mode automatically provides an oscillogram showing
the voltage and/or current waveforms.| It is very simple to measure harmonics and inter harmonics with the CA 8345, which is very easy to use as an analytical tool.
|
The CA8345 can be used to monitor all the power values (P, Q, D, etc.) in real-time over periods of varying durations. Measurement and analysis of all the power values measured enable you to perform a full power survey in compliance with the standards.| The phase relation between the voltages and currents is displayed with a vectorial diagram. The vectorial representation allows you to confirm that the instrument is connected to the mains.

With a simplified configuration

Energy valuation
The Qualistar Class A offers users all the measurements required to successfully implement energy efficiency projects and monitor electricity distribution.![Chauvin Arnoux CA 8345 Three-phase electrical networks analyser

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, the command signals will then be measured.

Interharmonics
The Qualistar Class A models can be used to measure and display the interharmonics, as requested in IEC 61000-4-7, for very precise analysis of all the disturbances on an electrical network. 

Monitoring

Trend
The trend graph shows the variations of the parameters measured over time every200ms.

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 uploads, these instruments can record ½-period values covering more than half an hour and the waveform of the signal (three-phase voltages and currents).

Communication
In addition to using media such as SD cards and USB keys, it is possible to recover the measurements and communicate with the instrument remotely via USB, remote links,  Wifi (direct or via server), or RJ45.
There is no limit to the accessibility of the measurements.

IRD Server
All our IT networks are protected against external attacks.
Thanks to the provision of access to our IRD server, a single authorized IP output address allows you to transmit your measurements all over the world.
SCPI commands
With an integrated interfacing software layer, it is possible to control your instrument via its own software application. SCPI commands are available for all the instrument’s functions.
Data files in JSON format
Saved in JSON format, all the recordings are accessible and can be processed with a third-party and/or proprietary application.

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 analyzer 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 determines whether corrective action needs to be taken. This action may take different forms: resizing of a transformer,  implementation of filtering systems, replacement of faulty equipment, etc. This analysis helps you to act in the right place at the right time to provide the best solution. 

Electrical maintenance
The spread of electronic power supplies in industrial processes has led to an increase in harmonic disturbances on the electrical network which have a direct impact on the quality of the energy distribution. In the short or medium term, these disturbances may cause failures across all the electrical devices connected to the network in question.
Harmonic currents have negative effects on nearly all the components in the electrical system, creating new dielectric, thermal and/or mechanical stresses.
