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.

Meeting electromagnetic compatibility (EMC) requirements can be a significant challenge for engineers designing today's electronic devices. Traditional approaches rely heavily on EMC design rules. Unfortunately, these design rules aren't based on the specific EMC requirements for a particular device, and they don't usually take into account the specific function of the circuits or the many design details that will ultimately determine whether the device is compliant. This paper describes a design methodology that relates design decisions to the product's EMC requirements. The goal of performance-based EMC design is to ensure that electronic designs meet EMC requirements the first time the product is tested. More work needs to be done before this concept reaches its full potential, but electronic system designers can already derive significant benefit by applying this approach to products currently under development.

Recently, number of components and operation frequency rapidly increase in automotive systems. This often leads to EMI (electromagnetic interference) where automotive systems suffer from malfunctions induced by electromagnetic wave. This paper surveys various EMC (electromagnetic compatibility) compliance technologies such as EMI filter, EMI shielding materials, and spread spectrum clock generator. Their pros and cons are also explained.

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.

To comply with CE marking requirements, the electromagnetic compatibility (EMC) and low-voltage directive (LVD) tests are conducted on the sub-racks of International Thermonuclear Experimental Reactor (ITER) AC/DC converters and bypass switches. The EMC tests consist of a series of tests, including the electromagnetic interference test, the electromagnetic field immunity test, and the rapid transient burst immunity test. In the LVD test, the electric shock protection test, the xcessive temperature limit and heat resistance of equipment tests, and the fire spread prevention test are performed. This work presents and reviews the European Directive for EMC/LVD and introduces the methods of EMC and LVD tests for the sub-racks of AC/DC converters and bypass switches. It also evaluates the test method and results to meet the European Directive requirements for CE marking. The sub-racks of ITER AC/DC converters and bypass switches successfully pass the EMC and LVD tests.

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.

전자기적합성 전문위원회(TC 77 : Electromagnetic Compatibility)는 현재 IEC/TC중 에서 가장 활동이 활발한 TC 가운데 하나이다. 이는 거의 모든 산업 분야에 중요한 문제로 대두 되고 있는 EMC의 표준화를 담당하고 있기 때문이다. 이 글에서는 IEC/TC 77의 배경 및 업무 등 을 간단히 살펴 보고, EMC 표준화 전반에 걸쳐 관련되고 모든 EMC 규격의 바탕이 되는 '기본 E MC 간행물(IEC 1000 시리스)'의 현황을 알아 본다. 여기서는 IEC 1000 시리스 외에도 EMC 관련 이 많은 CISPR 규격 등 몇개를 포함시켰으나, SC 77C(HEMP) 관련 규격은 생략하였다.

In the industrial internet of things (IIoT) industry, including smart factories, there are many cases where electronic devices are complexly combined and installed due to the recent development of intelligent information technology. Electromagnetic waves generated from such complex facilities affect other devices and services, which can lead to safety issues. The problem such as electromagnetic interference (EMI) and electromagnetic compatibility (EMC) generated when controlling complex facilities is an essential element that must be solved, and the engineering basis for EMI and EMC must be established to foster the industry of complex facilities. Therefore, in this study, EMC & EMI engineering demonstration cases for solar power fixed facilities using the national standard guideline have been analyzed. The results show that the electromagnetic risk indices in the solar power facilities have been degraded up to control level, and a national EMC engineering system has been proposed for complex facilities.
