우리나라의 산업표준규격인 KS 규격에 건축용 전기설비 부분은 아직까지 국가 규격이 제정되지 않았으나 세계규격중 각국의 큰 관심을 갖고 제정하는 분야가 건축용 전기설비이다. 그 이유는 건축용 전기설비는 교류 1000V이하, 직류 1500V 이하의 고객측 전기설비기준을 국제규격으로 제정하고 있어 각국의 전기공사 방법이나 가전제품 등 일반 전기기기의 제품규격에 상당한 영향을 주고 있기 때문이다.

This Paper present about loop impedance measuring method by a comparison & analysis of the earthing systems in IEC60364. And comparing analysis about only considering a resistance and considering resistance & inductance. Result, For measuring of loop impedance than must measured resistance and reactance. And TT earthing system was lower fault current then TN systems, but an electric shock was higher then TN systems.

To apply the appropriate new grounding system to domestic power system, safety has to be guaranteed under the given circumstances. It is not possible to decide the safety of grounding systems by the experimental test because safety experiments directly relate to the human life and the installed electric machines. Therefore, the computer simulation program to decide the safety of grounding systems based on the IEC standard systems, has to be developed. This paper proposes the computer simulation based method to decide the safety of grounding system with the concepts of touch voltage, step voltage, human resistivity, and applied electric current according to the several conditions of human body located in the corresponding grounding systems. The proposed method is implemented by Matlab/Simulink and Visual C++ programming tools for its visualization.

With the increasing popularity of renewable generation systems and the advancement of power electronics, DC distribution systems have recently received considerable research attention. DC distribution has numerous advantages, including reliability, power quality, and efficiency. Owing to these advantages, DC distribution has been applied to data centers and power quality-sensitive electronic load conditions. Because grounding electrodes in DC are much more susceptible to corrosion than in AC, the IT system defined in IEC Standard 60364 may be a good candidate for an earthing method for DC distribution systems. In addition, IEC Standard 61557 specifies the requirements for insulation monitoring devices (IMD) for protection of the IT system, which continuously monitors the insulation resistances between the power lines and the earth. This paper discusses the development and evaluation of IMD to promote the reliability of distribution systems and increase safety of humans and facilities.

IEC 60364에서 규정하는 접지방식 중 IT접지시스템은 접지극에서의 전식문제가 없으므로 DC배전계통에 가장 적합한 것으로 전망되고 있다. 그러나 IT접지시스템의 장점을 확보하기 위해서는 운전 중인 전력선의 절연상태를 지속적으로 감시할 필요가 있으며, IEC61557은 IT접지환경에서 전력선의 절연상태를 감시하는 활선절연저항감시장치(Insulation Monitoring Device; IMD)를 설치할 것을 규정하고 있다. 본 논문에서는 활선상태인 전력선의 절연 저항을 모니터링 함으로써 IT 접지시스템의 안정성을 증진시킬 수 있는 활선절연저항감시장치를 개발하고 성능을 검증한다.

This paper presents a loop impedance(inner loop impedance & external impedance) measurement method in TN system. When the measurement of a loop impedance then the measurement result have a some error by load condition. In this paper suggest the loop impedance measurement on actual loading condition by two experiment. one was laboratory condition and the other was the actual measurement on site. Analysis result, measuring error by load condition has not effect on measuring loop impedance.

This paper write about earth system for the prevention electric shock and a protection of equipment in england. The IEC60364 and BSI(British Standards Institution) define earthing method(IT, TT, TN-C, TN-S, TN-C-S)-BSI is british standards and in case of england almost use the TN system. TN system can classify TN-S & TN-C-S(PME). The findings on survey in england are used the TN-S system and TN-C-S system about 70% and residue 30% are used TT system and IT system from the exiting state of things.
