The Telecom Engineering Centre (TEC) has brought out a standard for the electromagnetic interference (EMI) evaluation of telecommunication terminal equipment including telephones. A test methodology was devised for the evaluation of telephones, using a sound pressure level meter as performance monitoring equipment for quantitative assessment of equipment under test (EUT) under radiated susceptibility conditions. The test methodology devised and the problems faced during the evaluation are discussed in this paper. A review of the TEC standard to take care of most possible real life situations is also discussed.","PeriodicalId":444507,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility '99 (IEEE Cat.

Each of theses drives are controlled by an electronic rack containing a microprocessor card besides other cards. System hanging and bus hog problem in the processor card was reported in many drives during commissioning stage in a major steel plant where a number of drives systems had been supplied. The problem was studied in depth. Bus hog problem in the processor card arises when the devices addressed by the processor fail to respond within a specified time. The processor IC due to its excessive heat dissipation and associated noise generation was found to be the cause of the problem. In the processor boards of the drives systems where the above problem had been observed, the processor IC was changed from the existing NMOS version to a CMOS version as a CMOS processor IC dissipates less power during operation and generates less noise. After replacing the processor IC, drives systems have been functioning smoothly for 18 months and no hang up and bus hog problems were reported.","PeriodicalId":444507,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility '99 (IEEE Cat.

The EEA comprises in total eighteen states. Outside the EEA the directive is also effective in Switzerland. After a short introduction to the EMC directive, the different bodies involved in the EMC field as defined in the directive are explained. Special attention is given to the \"Guidelines of the European Commission on the Application of the EMC Directive\", which is in practice as important as the directive itself. Following this a flow chart for the certification procedure is presented. A table of different product families together with the respective EMC standards is given whose limits for RFI emissions and susceptibility to interfering RFI must be met. Finally the enforcement practice of the German authorities and their experience after a year of effecting the EMC directive are described.","PeriodicalId":444507,"journal":{"name":"Proceedings of the International Conference on Electromagnetic Interference and Compatibility '99 (IEEE Cat.

The placement of filters and waveguides along with openings like doors, windows and cabling layout have a considerable deteriorating effect on shielding. The effectiveness of the chamber selection of filter is based on power handling capacity, attenuation characteristics and ease of grounding with respect to the chamber. Ferrites are used for suppression of unwanted signals. The focus of this paper is to describe on site shielding effectiveness measurement experiences.
