In France, an important contribution to sustainable development is being made in the form of improved control of energy consumption. EDF (Electricity de France) is installing power quality meters on the national grid to monitor conformity to the EN50160 standard for power quality.
In Project ‘MAGIQ’, data will be gathered by a network of power quality analysers and processed using software enabling the automation of each task.
With this power quality analyser, EDF is offering a solution for improving the quality of the measured points. The collaboration with Legrand is based on a continuous evolution of the standards and methods of analysis.
For those in the energy industry, requests for power quality monitoring are appearing everywhere:
The project is a symbol of reliability, a new way to satisfy customers and also a step towards sustainable development. Indeed, the final aim is the drastic reduction of the portion of energy which is not transformed into useful energy.
Alpes Technologies, a group brand of Legrand, is presenting this solution for analysing the quality of electrical supply networks according to the standards currently in force, EN50160 and IEC61000-4-30.

This webinar is a training introduction to thermal imaging, or thermography. Topics covered will be:
There will also be an opportunity to ask questions about your application and where to find relevant documentation on thermal cameras and common applications.
During this event, you will discover what thermal imaging and thermography are and how they work. Examples of the most common industrial applications will show you how thermography can help you save costs in your plant. You will see how to use thermography to find problems and faults in everyday inspection of equipment and processes, and how to use software for analysis and comprehensive reporting of your findings in the field. There will also be an opportunity to ask questions about your application and where to find relevant documentation on thermal cameras and common applications.
This webinar will present the essential concepts required in order to develop a complete Power Quality analysis of an installation. You will learn about the perturbations that affect to the power supply considering the amplitude, frequency, harmonic distortion, flicker and unbalance from a measuring and quantification point of view. You will also learn about the applicable international standards (EN50160, IEC61000-4-30), which are the reference for the power quality studies. Finally, you will get indications about the instruments for power quality recording and analysis, their characteristics and applications.
In this webinar, the recent addition of the energy efficiency modules to the RETScreen International Clean Energy Project Analysis Software will be introduced. RETScreen is a unique decision support tool developed with the contribution of numerous experts from government, industry, and academia. The software, provided free of charge, can be used worldwide to evaluate the energy production and savings, lifecycle costs, emission reductions, financial viability and risk for various types of energy efficient and renewable energy technologies (RETs). The software also includes product, cost and climate databases, and a detailed online user manual. Other tools include: a case study based college/university-level training course and an engineering electronic textbook. The webinar includes an introduction to the RETScreen energy efficiency modules, a demonstration and a Q&A session.
Au cours de ce webinaire en français, vous pourrez suivre une présentation des nouveaux modules d’analyse pour les projets d’efficacité énergétique de RETScreen le logiciel d’analyse de projets d’énergies propres. RETscreen est un outil unique d’aide à la décision développé en collaboration avec de nombreux experts de l’industrie, du gouvernement et du milieu académique. Offert gratuitement, il peut être utilisé partout à travers le monde pour évaluer la production et les économies d'énergies, le coût, les réductions des émissions, la viabilité financière et le risque de différentes technologies d'énergies renouvelables et d'efficacité énergétique. Le logiciel (disponible en plusieurs langues) inclut des bases de données de produits, de projets, hydrologiques et climatiques, un manuel de l'utilisateur en ligne, ainsi qu'un cours de formation de niveau collégial et universitaire basé sur des études de cas, incluant un e-Manuel d'ingénierie. Le webinaire comprend une présentation commentée, une démonstration et enfin une session de questions/réponses.

This webinar reviews the concept of reactive power and highlights problems that can occur if too much reactive power is drawn from the supply system. Depending on the load type (slowly or fast varying, small or large power loads) and the network (weak or strong networks, harmonics present or not), different phenomena can occur; from simply putting extra stress on supply cables to power outages bringing production lines to standstill. It is shown that for different applications different reactive power compensation solutions must be applied - special attention is paid to fast reactive power compensators and their use. Selecting the right solution can bring substantial (energy) savings to the users.
