This webinar discusses some of the power quality contracts and classification systems used by distribution companies. It will show the different contracts used around the world by some groups of customers and utilities. It also discusses the roles of the regulator when allowing the market to agree on premium power quality contracts.
This webinar also describes the possiblity of classification of power quality at the point of supply for the most important power quality aspects (interruptions, voltage dips, harmonics, voltage fluctuations).

The Power Quality Survey was conducted by the European Copper Institute (ECI) to investigate the consequences for EU industry of poor power quality among industrial sectors for which electrical energy is critical. These consequence amount to >€150bn annually, are mainly [>90%] experienced by industry and caused by power interruptions (dips, surges, transients and short interruptions). These losses represent a significant [>5%] proportion of the net profits made by the sectors under review.Read full story
Traditionally electricity networks have been built to transport electrical energy generated by large, central placed, power production units. The new, relatively small, distributed generation (DG) units are usually connected to distribution networks, not designed to host power generators. Most studies confirm that 10-15% penetration of DG can easily be absorbed in the electricity network without major structural changes.Read full story
