This paper outlines the administrative obligations contained in the European EMC Directive, 2004/108/EC, with particular reference to the Declaration of Conformity (DoC). It considers the mounting evidence, including that resulting from European market surveillance campaigns, that insufficient attention is paid to ensuring that the supporting documentation is not only in place, but also up to date...
Electronic equipment comprising safety functions must be subject to a risk analysis, where the potential impact of all kinds of environmental influence from the surroundings, including the influence from the user environment and the user self, is to be identified and handled. The HALT approach (in this case denoted High Amplitude Limit Test) provides an opportunity, where the iterative testing and...
In most cases the results of susceptibility tests based upon pass/fail criteria are purely qualitative; because of this reason it is impossible to define the susceptibility safety margin defined as the difference between the 50% probability of malfunction and the probability of the most critical test conditions. With the help of Logistic Regression one can give a quantitative interpretation also to...
Large installations use different shielded, or EMC, zones to separate regions, such as in the integrated mast onboard naval vessels. Multiple cable transits are being used as a standard decoupling measure between the zones. Cables shields are connected in the cable transits with the objective to short-circuit cable sheath currents to the wall. Measurements have been performed to check the quality...
This paper presents new quantitative EMC (ElectroMagnetic Compatibility) design guidelines at board, cable and enclosure level to reduce radiated emission in the frequency range from 30 MHz to 6 GHz. These new design insights are the outcome of extensive 3D electromagnetic simulations on a general modelling framework for electrical architectures. They can be used during the early phases of system...
We present in this paper an overview of conducted and radiated sources that could be considered as potential intentional electromagnetic interference (IEMI) sources against critical infrastructures associated with power systems. The sources are classified according to the commonly addressed criteria in IEMI. In addition, to assess their potential risk, reported IEMI sources are classified according...
The effect of Electric Fast Transients (EFT) phenomena in an Ethernet interface set-up is investigated in order to get more insight in coupling and interference mechanisms, robustness and susceptibility levels of a typical Ethernet installation on board of a naval vessel. It is shown that already a small EFT pulse is capable of disturbing or disrupting Ethernet communication at protocol level, which...
Within the last decades, the threat of fast transient electromagnetic pulses is rising, especially since new technologies of sources with higher mobility are available. Therefore, it is important to determine the threshold levels for the breakdown of electronic systems and its subsystems and components. For the determination of these threshold levels, time consuming measurements are necessary leading...
Interfering signals collocated to a radio communication system can degrade the system performance severely. To quantify this degradation by measuring the interfering signal is a difficult issue. Traditionally, the average interference power (the root mean square (RMS) value of the interfering signal) is measured and used as a measure of the impact on a digital radio receiver. However, it is well-know...
