BRIEF DESCRIPTION

Complex and large systems can be subdivided in a lot of subassemblies. The aim of the project is to start with an EMC risk analysis, in order to locate the most sensitive or susceptible subsystems concerning EMC. Given this analysis, it is the aim to look for the testing of these subassemblies. Combined with the installation guide rules of the manufactures, this should prove evidence of conformity for the complex system.

Electromagnetic fields due to lightning discharges

PROJECT START&END DATES : Start : 1.01.00 – End : 31-12.03

TOTAL FUNDING : 75 kEUROS

BRIEF DESCRIPTION

The knowledge of lightning current parameters either comes from direct measurements, using high instrumented towers, or is based on quantification of lightning electromagnetic fields from which lightning currents are inferred adopting some empirical or theoretical relations.

More recent experimental observations on high telecommunication towers as well as theoretical analyses suggest, however, that the lightning current data obtained by means of instrumented towers might be appreciably affected and 'contaminated' by the presence of the tower itself. Therefore, the adequacy of the statistical lightning current data which is being extensively used by researchers today becomes questionable.

The major aim of the proposed research program is to re-evaluate the available statistical data and extract the 'primary' data on lightning, undisturbed by the characteristics of the struck object.

Another important problem which is dealt with in the present study is the estimation of lightning current parameters from measured electromagnetic fields. This issue has gained interest in the last few years with the widespread diffusion of the so-called lightning location systems (LLS). Besides providing lightning flash density maps within their working area, these systems use the field data to estimate peak lightning currents and to provide relevant worldwide statistics. The proposed research study and the experimental recordings will be used in improving LLS lightning current parameter estimation, since it can be expected that LLS will become more and more important in the near future and they will provide an enormous amount of worldwide data.

Use of the LV distribution power network for the access to a telecommunication network

INVESTIGATOR’S NAME

Prof. M. Ianoz, Dr. F. Rachidi, Mr. E. Marthe, Ph.D. student, Swiss Federal Institute of Technology, Lausanne, Switzerl

PROJECT START&END DATES : Start : 1.10.99 – End : 30.09.02

TOTAL FUNDING : 125 kEUROS from the Foundation for Projects and Studies of the Electric Economy (Switzerland)..

BRIEF DESCRIPTION : Distribution power lines have been used for long time to transmit specific information pertaining to the network operation or to various services which electric utilities are offering to their customers. The new idea is to extend the frequency range of the signal transmission up to 30 MHz and to increase the speed up to 3 Mbits/s. EMC emission problem can be present at three different levels: indoor, street or global environment level. The difficulties to determine the level of such disturbances are connected to the complicated and very big variety of the possible arrangements of the LV network in a house and to the small dimensions of the rooms which does not permit to perform measurements at distances from the disturbance source larger than about 1 m. A double approach using numerical modeling (like for instance the use of the NEC) and real scale measurements on an experimental network will be performed.

TOTAL FUNDING 11000000 GDR (33000 EURO)

BRIEF DESCRIPTION

Current Optoelectronic and Photonic technologies are at the point where their integration into large-scale multistage interconnect architectures is both feasible and beneficial in order to reduce the comlexity and increase the throughput of each switching node.In order to achieve these it is very important to the designer to be familiar with possible interference problems in such installations.

Since an electronic interface is used to modulate the signal carrier in an optoelectroic device, circuit or system, it is possibe for interference phenomena to disrupt the operation.

Intereference phenomena have been observed in optoelectronic, acousto-optic or magneto-optic systems commonly used in industrial commerical or military applications.

The aim of this project is to study such phenomena and analyse their effects on large optoelectronic (photonic) systems.

BRIEF DESCRIPTION:

The knowledge of the field makes possible the prediction of interference, the introduction of mitigation measures into coupling path, or can be used to improve immunity of the potential victim.

Summarising the results of the previous work, the project aims to develop a software capable to analyse electromagnetic fields using variant of the finite element method for space - time dependent operator. The same code can be used for the calculation in both antenna and scattering mode firstly for cylindrical than planar and arbitrary multi-layer geometry.

The investigations are focused primarily on the radiated type of interference phenomena. The results will be applied in resolving EMC problems in telecommunication systems: transmitters, mobile transceivers, coupling between lines (power and signal cables), transients on lines and lightning threats.

BRIEF DESCRIPTION

The EMC research group at Ancona University has developed some approaches to

investigate the ESD phenomena in different situations: ESD current injectionon PCB traces with linear and non linear loads, ESD penetration into shielded enclosures through slots due to a direct ESD application or to a radiated ESD fields. The proposed project is the continuation of this research and will deal withthe impact of ESD on complex structures as a metallic box filled with PCBs and subsystems.

A suitable technique to perform the analysis will be a hybrid method basedon the combination of the marching on in time procedure to solve integral equations and FDTD in order to get an high computation efficiency. All theoretical results will be validated by measurements carried out in our EMC laboratory. Also the stocastic aspects of ESd will be investigated.

BRIEF DESCRIPTION

When many radio sources exist within a confined area the wideband voltage induced onto a nearby conductor may contain pulses whose amplitude is many times that due to one radio source alone. This scenario is becoming increasingly prevalent as the density of usage of mobile radio communication systems such as GSM, TETRA and DCS1800 increases. The study aims to investigate the characteristics of the total em field due to such a population of diverse radio systems. A related study (QV) being carried out at the University of York is investigating the coupling of such a threat field

into distributed systems. (UK11)

Manmade radio noise is a particular manifestation of radio interference generated as a consequence of a wide variety of man s activities. In a previous study, a measurement system was implemented which was optimised for measurement of wideband radio noise and interference. A suite of software was also written to analyse noise measurements in terms of APD, NAD, PSD, PDD etc. A further system has now been developed based on the use of a fast sampler and its use is being investigated for

various noise and interference studies.

PROJECT START & END DATES Aug 1998 - Aug 2000

TOTAL FUNDING (INDICATE CURRENCY) £210k pounds sterling

BRIEF DESCRIPTION

The project aims are:

* to develop methods of making quantitative predictions of the electromagnetic compatibility (EMC) of electronic equipment, using limited information available at an early stage in its design;

* to estimate the uncertainties associated with these predictions;

* to implement these methods in design software to demonstrate their

practical application to electronic design.

The project aims to enhance the understanding of the electromagnetic compatibility of equipment so that predictive estimates, with known levels of uncertainty, can be made at an early stage in the design process. The methods will be implemented in software tools for evaluation by designers. The project will both enhance academic knowledge of EMC and help industry to reduce the cost of designing and testing for EMC.

Geometric generalization of Transmission Line Theory to Nonuniform Transmission Line Structures

Dr. F. Gronwald

PROJECT START & END DATES Start: October 1998

TOTAL FUNDING Not applicable

BRIEF DESCRIPTION

In the framework of EMC one often encounters the problem of determining the electromagnetic susceptibility of systems connected by transmission line structures. Corresponding solution procedures often involve ordinary transmission line theory. However, in case of nonuniform transmission line structures the assumptions made in transmission line theory, notably the existence of the (quasi)-TEM-mode or the neglect of radiation, generally are no longer valid.

Therefore we develop analytical methods to generalize transmission line theory to nonuniform transmission line structures. Our main tools are perturbative and differential geometric methods that are to be included into Maxwell’s theory.

Alimpie Ignea            Project Leader

PROJECT START & END DATES: 2000-2002

TOTAL FUNDING:  10000 USD

BRIEF DESCRIPTION:

In principle the passive circuit components do not generate intermodulation distortions but, due to the non-linearities presented by their characteristics, the generation of high order armonics and of intermodulation distortions is possible.  Due to corrosion formation of some diode parasitic structures type metal - oxide ("rusty screw" effect) the phenomena can be present at relatively low frequencies as well but especially at high frequencies, where at magnetic materials and dielectric ones relaxation phenomena can appear additionally.

The subject approached aims to establish a model for the non-linearities specific to some components characteristic to high frequencies (cable, connectors) and to elaborate a practical procedure to measure intermodulation distortions generated.
