Standard verification campaigns

Energy valuation

Offers all the measurements required to successfully implement energy efficiency projects and monitor electricity distribution

Shockwaves

Usually caused by lightning, are spectacular instantaneous electrical voltage surges, and they also propagate in the digital network; can withstand shockwaves up to 12 kV which are sampled every 500 ns.

Line carrier signal measurement

In the harmonic analysis function, there is also a mode for monitoring carrier currents, and after defining their frequency, the command signals will then be measured.

Interharmonics (harmonic mode)

Can be used to measure and display the interharmonics, as requested in IEC 61000-4-7, for very precise analysis of all the disturbances in an electrical network

Monitoring made easy

Trend

The trend graph shows the variations of the parameters measured over time as fast as 200 ms

Alarms

Alarms set points can be programmed 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

True InRush

For tests when starting up loads, it can record ½-period values covering more than 30 minutes and the waveforms of the signal can be captured

Versatile communication

In addition to using media such as SD cards and USB drivers, it is possible to download the measurements and communicate with this instrument remotely via USB, remote links, Wi-Fi (direct or via server), or the RJ45 (Ethernet connector).

The web server

This analyzer is 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, etc.).

IRD server

The IT networks are protected against external attacks. Thanks to the provision of access to the 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 this 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.

Meeting standards

The International Electrotechnical Commission (IEC) IEC 61000-4-30 Edition 3.1 standard. This standard defines:

• The methods for measuring the quality parameters for the supply of power to electrical power networks
• 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.

The EN 50160 standard characterizes the quality of the voltage supplied. It presents the different types of disturbances which may affect the voltage on a network. It lists the parameters to be monitored and defines how long the parameters should be monitored for. With the DataView® 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.

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.

This is caused by the power supply 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 two parameters calculated from the power supply 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 two hours

Applications

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. Voltage quality analyzers can be used to detect and qualify each disturbance type: outage, voltage surges, and sags, flicker, THD, voltage variations, transients, etc.

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, billing data is compared with the actual measurements to determine whether corrective action needs to be taken. This action may take different forms: resizing a transformer, implementing filtering systems, replacement of faulty equipment, etc. This analysis helps you understand and act at the right place and time to provide the best solution.

The increase in electronic power supplies in industrial processes has led to increases in harmonic disturbances on electrical networks which have a direct impact on the quality of energy distribution. These disturbances may cause failures across all the electrical devices connected to the network. Harmonic currents have negative effects on nearly all the components in the electrical system, creating new dielectric, thermal, and/or mechanical stresses.
