A study of solutions to EMI of computer monitoring and control system in hydropower plant
Tập 2 - Trang 716-720 vol.2
Hydropower plant is a large energy conversion location, which suffers strong EMI. Its computer monitoring and control system works under a bad electromagnetic environment. Aiming at raising its ability against EMI, this paper makes a study on the solutions with the applications of some basic EMC techniques. The generator busbar, primary device, auxiliary equipment and transmission line are discuss......

Simulation of switching noise in multi-layer structures using generalized transmission line equation method
Tập 2 - Trang 1026-1031 vol.2
This paper discusses the use of the generalized transmission line equations (GTLE) for the simulation of switching noise distribution in multi-layered packaging structures. After a brief discussion on the formulation and its application to a simple dual trace transmission line, two-layered plane and two-layered plane with four drivers and traces, the method has been applied to a complicated fourte......

Update on power line telecommunication (PLT) activities in Europe
Tập 1 - Trang 17-22 vol.1
Due to recent deregulations in the EU utility market, it is tempting to compete with classical telecom providers now over power lines, e.g. for broadband internet access in mostly residential areas. PLC (power line communications, sometimes called PL-T standing for telecommunications) uses unshielded, 230 V/50 Hz low voltage distribution cables inside and outside of buildings as transmission mediu......

Reducing high frequency conducted noise
Tập 1 - Trang 334-339 vol.1
This paper investigates the effectiveness of commercial AC power electromagnetic interference (EMI) filters, RF bulkheads, toroids, and ferrite beads in reducing common mode conducted noise. At frequencies below 30 MHz, commercial and military specifications only provide for conducted noise limits, which indirectly causes an increase in environment noise when the noise is radiated by long power or......

The use of via holes for controlling the crosstalk of nonparallel microstrip lines on PCBs
Tập 2 - Trang 633-638 vol.2
In this work, the metal filled via holes are constructed into fences between the nonparallel microstrip lines to control the crosstalk. In practice, coupling between nonparallel traces is common. On the other hand, via holes are easy and inexpensive to build using the current fabrication process for the commonly used PCBs. The effects of the via holes for alleviating the coupling are investigated ......

Effect of cable shield resistance on the electromagnetic coupling of lightning to a cable above a ground plane
Tập 1 - Trang 77-80 vol.1
An analysis of the voltage induced onto the inner wire of a cable above a ground plane shows that this voltage does not depend on the resistance of the cable shield at frequencies below the R/L break frequency, where the current is limited by the shield resistance and above the R/M break frequency, where the current is limited by the shield's self inductance. In the frequency range between the bre......

On the measurement of shielding effectiveness in a mode stirred chamber
Tập 1 - Trang 383-388 vol.1
In the work presented here, the authors investigate how the isotropic shielding effectiveness measured in a mode stirred chamber (MSC) varies with probe type and position for a generic avionics bay. The measurements are made using six different probes in six positions. In the analysis, the measured received power is compared to the theoretical exponential distribution with good agreement for the e......

An imaging system for EM emitting sources with time-domain sampling
Tập 1 - Trang 61-64 vol.1
In this paper, we propose a passive imaging system for noise source identification of digital circuit using time-domain waveform sampling. The fundamental concepts are based on optics theory. A waveform of a diffracted field on an entrance pupil is acquired by a digital oscilloscope. The phase distributions on the entrance pupil for each frequency are calculated by using Fourier transformation of ......
