In order to ensure the electromagnetic safety of a complex facility equipped with a variety of electric and electronic equipment, the European Union (EU) has enacted and applied the Electromagnetic Compatibility Directive (EMC Directive 2004/108/EC) to a fixed installation. This paper introduces the regulations and techniques related with electromagnetic compatibility (EMC) engineering applied to a fixed installation, which is used to prevent a malfunction of critical equipment and systems caused by unwanted electromagnetic waves and to operate the facilities with stability.

In modern system, electromagnetic environment are going worse with advancing electric and electronic technology, and this electromagnetic environment affect modern electric train system at the point of the safety problem. Therefore, each distributed system that is consisting electric train system have to prove there own electromagnetic compatibility through the field test. These distributed system can be considered as power supply system, signal & communication system and train system. In this study, essential field tests for electromagnetic compatibility of train system based on IEC national standard are suggested.

Nowadays many two-wheeled motorcycles are used in leisure and express delivery industries. But studies of the electromagentic compatibility on motorcycles have seldom been performed and published. This paper has studied the electromagnetic safety of motorcycles considering international and domestic regulations and standards. Also, a series of experiments have been performed to evaluate the level of electromagnetic compatibility of commercially available motorcycles. As a result, detailed experimental procedures are proposed to secure the electromagnetic safety and can be used to confirm or revise the Korea Motor Vehicle Safety Standards.

This paper presents methods to improve the effectiveness of electromagnetic shielding. The slit appears in an enclosure's surface to ventilate. Slits may also appear due to power supply lines or to serve as a communication link between electronic circuits inside and outside the box. We simulated electromagnetic radiation in different conditions in order to propose a method to improve the effectiveness of electromagnetic shielding to ensure electromagnetic compatibility using CST software (Computer Simulation Technology).

Recently, the amount of electrical and electronic systems is increasing rapidly with the development of advanced vehicles such as ADAS, smart cars, connected cars, automated driving systems. It is necessary to examine the electromagnetic compatibility of vehicles equipped with those systems. The standards and regulations for examination of electromagnetic compatibility have been established and revised according to newly introduced electrical and electronic systems. They are administered in some different international standard associations such as ISO, CISPR, UN/ECE and are somewhat complex and bulky. In the study, the improvements and changes in them are tracked and analyzed chronologically. Research of the history of them will be helpful for understanding progress and forecasting the direction of development.

It is quite essential that requirements allocation and analysis would be done for the electromagnetic compatibility (EMC) of all units when designing a satellite. Although KOMPSAT-2 inherits relatively large portions of the electrical designs from KOMPSAT-1, it has a new instrument and different combinations of sensors and actuators as well as their driving circuitry. Many requirements for the electromagnetic compatibility were modified and newly allocated for KOMPSAT-2. Naturally, they must be justified through analyses from the early stage of the program. In this paper, the EMC compatibility requirements for KOMPSAT2 are presented and verified for their suitability. In addition, some results, which were obtained from various analyses, are presented and discussed.

The transverse electromagnetic (TEM) cells are widely used for electromagnetic compatibility (EMC) testing and field probe calibrations. We propose the verification of TEM mode with statistical method using a four-port TEM cell. The verification results are compared with Normal, Rayleigh, and Gamma distribution. As a result, the 75 % quantile of the Rayleigh distribution is excellent agreement with the true quantiles for a number of calibration points.

This paper describes a measurement method for electromagnetic field strength of power-line communications(PLC) modem. First it outlines the technology used in PLC modems, and the technical regulation being offered to the technology, from the point of view of its effect on electromagnetic compatibility (EMC). The radio spectrum needs protection from other interferers, and there is a regime in place to provide this protection. Difficulties in achieving compatibility between the requirements for radio protection and the requirements for operation of the PLC modem mean that there is no consensus as yet as to how PLC modem components can be made compliant with EMC requirements globally. It is concluded that there is a measurement method according to CISPR standards which satisfy requirements in domestic regulation.
