Electromagnetic compatibility issues in industrial equipment

The aspects covered by the EMC regulations, in particular European Directive 89/336/EEC, are numerous and often complex. In this article, the authors have tried to summarize the standards recalled by the Directive for industrial and residential equipment and to emphasize some relevant measurement and design problems. The picture is surely vague and incomplete, but one point should be evident: EMC is a real problem and finding solutions which are technically suitable and economically competitive is today's challenge for design engineers.

La función de ocio en el área metropolitana de Valencia

This report analizes the leisure function in the AMV accross the location of three kinds of essential equipment : second homes, campings and hotels that shape the residential equipment; restaurants and coffee houses that constitute the relation equipment; and finally the sports facilities. There are a veritable leisure function integrated in the AMV, that depends on potential abundant clientele; its essential parts are the residential leisure settlements that have three notable locations : the seaboard and the areas north-west and south-west.

Emissions and Energy Conservation in Residentdal Oil Heating

Emissions from oil-fired residential heating equipment can be reduced by improved steady running and cyclic efficiencies. Techniques which reduce the heating demand (thermostat cut-back) or reduce envelope losses (chimney damper) lead to reductions in SO2 and NO emissions proportional to the fuel saving. Higher savings in CO and particulates result from cyclic modification. Reductions in nozzle size lead to an increase in unit cycle duration, reducing the off-cycle losses, with emissions reduced similarly. Changing the thermostat anticipator yields little reduction in fuel, SO2 or NO, but significantly reduces CO and particulate emissions, by decreasing the number of cycles. Improved burner performance, with combustion at low excess air, offers the largest fuel savings, with commensurate reductions in SO2 and NO, and greater reductions in CO and particulates.

The effect of frequency and voltage on equipment

THE effect of low frequency and low voltage on power plant equipment, as well as on residential consumers' equipment during periods of trouble on power systems, is considered in this paper.
