Crosstalk electromagnetic interference occurs in on-board electrical wire bundles of aircraft electrical systems under the effect of external electromagnetic fields. Efficient reduction of crosstalk and elimination of their propagation paths in wire bundles can be achieved by shielding the conductors in the bundles and the bundles as a whole without breaks and discontinuities between the shields and housings of electrical connectors. The shielding of conductors in bundles does not eliminate the crosstalk completely, which can propagate through the contacts of electrical connectors. For estimating the influence of electrical connectors on the levels of crosstalk in electrical system circuits, their experimental studies should be carried out. In the course of these experimental studies, the interference voltage induced at the receptor contacts when voltage is applied to the source contacts in the specified frequency band is measured. The results from experimental studies of crosstalk for various types of electrical connectors in a specified frequency band make it possible to evaluate the resonance nature and levels of crosstalk interference levels depending on the relative position of the contacts and frequency.

Modern Era

In the modern era, due to several confliction or uncertainty in the aircraft, Electromagnetic Interference (EMI) or Radio Frequency Interference (RFI) issues occurred, frequently. The main reason behind it several disturbances generated by an external source which imitate wireless circuits with the help of conduction, electrostatic coupling, and electromagnetic induction. These disturbances may decrease the performance of the circuits or sometimes fully stop the operations. Main challenges in EMI are modeling and simulation for modern and future wireless communication systems and networks taking into account nonlinear interference effects. In this paper, overviews of several issues of EMI or RFI are illustrated.

Electromagnetic interference effects caused by electric power lines on neighboring metallic utilities such as water, gas or oil pipelines became a major concern due tosignificant increase in the load and short circuit current levels needed to satisfy the load requirements. Another reason for increased interference levels originates from the environmental concerns, which impose on various utilities the obligation to share common corridors. This paper presents three different scenarios of a pipeline in which all types of electromagnetic interferences (coupling) will be investigated and their effects on the pipeline will be predicted. The level of the calculated voltage, owing to each type of coupling, depends on different factors (voltage level, length of parallelism, separation distance, soil resistivity, load current magnitude and pipeline coating). The effects of these factors are discussed; some factors such as the fault current level, separation distance and soil resistivities are found to exhibit a large influence on the pipeline voltage. To the best of the authors’ knowledge, the comprehensive analyses presented in this paper considering all types of interferences have not yet been publishedelsewhere.
