Walking around a dealer’s showroom for a few hours is usually sufficient to return home satisfied. However, things get more difficult when you have to decide what number of electrical sockets, switches, lighting points, computer connections, telephone sockets, etc. has to be fitted in each room. The e-tool “Checklist for the electrical installation in the home” changes this situation.

A concept often causing confusion
The 'smart grid' is commonly presented as an indispensable part of the future power system. It is claimed that a true liberalised electricity market with a high penetration of distributed generation will only be able to supply a high degree of power reliability if grids are made smart.
But what exactly is a 'smart grid'? Reading through some literature on the subject, one quickly discovers that it can mean many different things to many different people, often leading discussions to end in confusion.
A smart grid is neither a clearly defined single concept nor a single technology. Rather it is like a basket containing various combinations of balls. The context and the interpretation depend upon the user. Carnegie Mellon University recently published an article describing all of the various balls typically found in this metaphorical basket. Some of them represent innovations that are still in the development phase, while others stand for technologies which have already been applied for years.

Power supply systems and power industry in contemporary world are significant, if not the most important, sectors of any company, each country and the entire world economy.
The continuity of power delivery is of fundamental importance for all customers, particularly for the industry and public sector.That's why the issue of on-line monitoring and measuring of power consumption, electric power consumption, and selected power quality parameters becomes more and more important. The information and characteristics contained in this paper depict the capabilities of intelligent building systems.
The presented applications of intelligent building systems have an opportunity of significant development particularly with prospects connecting them with local networks in buildings or industrial facilities (Ethernet network) and global Internet web. That way the data on building power supply can be remotely analyzed, practically throughout the world.
