In part 2 of this 3 part series, a 4-step procedure is presented that you could use for evaluating retrofit energy saving devices. Whether you're a consultant, purchaser or a third party looking at these technologies, this method can be useful. The methodology has been developed based on the author's personal experience looking at these devices in the lab and in the field, while comparing them with vendor claims.

This webcast reviews typical problems that may be caused due to the presence of harmonics in an electrical network dd. 2006. Possible solutions are reviewed. Modern active filter technology present in the field is explained and field test results from this equipment are presented. It is shown that active filter technology can be used to tackle a variety of Power Quality problems and their use results in a more efficient exploitation of the electrical installations.

In this webcast, Erwin Mlecnik from the Belgian Passive House Platform introduces the subject. Passive Houses reduce final demand for heat by a factor of 10, and total energy consumption by a factor of 6. They represent one of the largest and most promising concepts to contribute significantly to sustainable energy. The webcast defines the Passive House concept, and introduces its principles. A few practical examples are given, and references to further information are introduced.

In this compact webcast, Marcel Didden from Laborelec shares a wealth of information and experience. If you're considering investment in a mitigation solution, this may be one of your best 15 minutes ever spent.Installing a UPS is in theory the easiest way to protect sensitive equipment to voltage dips. However, due to their considerable purchase and maintenance costs, UPS's are only installed on a structural basis with installations where the costs resulting from power supply problems are very high such as in hospitals or financial institutions.
Triggered by problems in industrial processes containing variable speed drives, solutions to protect equipment only against voltage dips are now commercially available. This webcast analyses the technical and economic considerations of different options to protect specifically against voltage dips, such as: Dynamic Voltage Restorer (DVR), Flywheel, Statcom and Active Front End.

UPS today are increasingly being used when organisations need protection from a variety of power disturbances. But what are these disturbances? And how do you go about choosing a UPS? In this presentation - the first in a series of 3 on secure power offered by MGE UPS Systems, we intend to answer these questions by defining the disturbances against which loads need protecting, by describing the key points of the UPS standards and by explaining more about the three types of UPS described in these standards.
This Webcast ends with recommendations on how the topologies require a design suitable for the particular application that is being protected. We will also cover briefly the subject of rotary UPS.
