Requirements for Local Regulations on EMF Produced by Electric Lines
Extremely low frequency (ELF) electric and magnetic fields (EMF) produced by electric lines are included in the environmental impact evaluation of electric lines. The definition of the corresponding local regulation is the responsibility of...
Experimental Characterization and Analysis of the IEC-61967-4 Test Setup
This paper deals with the evaluation of integrated circuits (ICs) electromagnetic emission. In particular, emissions from an IC output driver are analyzed from the point of view of total radiated power. Correlation between the driver output...
An Efficient Method for Analysis of Horizontal Wire Antennas Placed Above a Ground Plane
The unknown current distribution (UCD) and input impedance of horizontal dipole antenna above a conducting half-space are determined in this paper. To solve this problem the system of integral equations of two potentials (SIE-TP) and new si...
A New IEC Standard on the Measurement of Power Quality Parameters
Following an initiative from the French and the U.S. National Committees, the IEC Technical Committee TC77 charged its Subcommittee 77A (Low- Frequency Phenomena) with the development of a new standard on the measurement of power quality pa...
ESD Testing, Luck or Wisdom
Testing conform the ESD standard IEC 61000-4-2 (1995) is part of the EMC tests that have to be carried out to comply with the overall EMC requirements of the generic or product related EMC standards. When all testing is performed according ...
Assessing the Immunity of Digital Equipment using the Emission Spectrum
The immunity of digital hardware to radio frequency interference is not adequately assessed by current EMC immunity test methods. A technique for quantifying the immunity of digital equipment using the characteristics of the re-emission spe...
Electromagnetic Compatibility of Systems for Train Movement Control on Electrified Railways
The aim and purpose of the experimental research in the rail tracks disturbances caused by the traction current was to determine the steady, time and place independent statistical properties for the interfering signals and to develop an ade...
Low Frequency Magnetic Field Inside a High Speed Train with A.C. Electrification: Field Calculation and Mitigation Techniques
Extremely low frequency (ELF) magnetic fields produced by 50 Hz currents flowing in the conductors of the a.c. electrified railway traction line are calculated inside a train by numerical techniques. Shielding techniques are then analysed i...
Investigation of Low Frequency EMI Produced by Inverter-Fed Linear Induction Motor Drives in Railway Systems
The goal of this paper is to perform a characterisation of electromagnetic emissions produced by power converters feeding a linear induction motor drive used in railway systems. The lack of a standard measurement site has been taken into ac...
Conducted EMI in a High Power Railway PWM Linear Induction Motor Drive: Theoretical and Experimental Investigation
This paper deals with the evaluation of conducted Electromagnetic Interference (EMI) produced by power converters in very large size drives, in order to get a good understanding of conducted emissions behaviour of the system. For achieving ...
