  • The efficiency and performance of electric facilities in electric railway tunnels are quite important factors for operation and maintenance of railway since most of maintenance works for railways are doing during the night. Specially, in the railways like Gyeong-Chun Line passing through many mountains, many parts of railways are constructed with tunnels. So, this paper proposes the efficient electrical installation design scheme for railway tunnel considering the system performance, economics, and the reliability of power supply to tunnel electric facilities. Finally, the proposed design scheme is implemented to the tunnel design for Gyeong-Chun Line (Electric Railway).

  • Street light facilities, which are easily accessible, can be in danger of electric shock when water percolates the facilities especially in summer. In case deteriorated facilities are not checked regularly, they can cause accidents such as electric shock. We should consider regional characteristics to prevent this kind of accidents. In this paper, we analyzed the problems according to the facilities through the research on the actual conditions. We also analyzed the facilities by region and the standards by the conditions.

  • The effect of air pollution on the distribution facilities was investigated. In order to evaluate the pollution level in the metropolitan area, contaminated specimens were analyzed with various technique such as ICP-AES, EA, and so on. The contaminants on the surface of the distribution line or insulators were combined with approximately 10 percent of organic and 90 percent of inorganic materials. We found out that the electric facilities were affected by the contaminants on the surface of the facilities.

  • Latest development of ICT makes building, including houses, factories and public facilities, more intelligent and automatized. It follows that a wide variety of electric and ICT installations are adopted along with micro electronic equipments. Corresponding to such changes, the frequency of lightning increases due to the abnormal climate. The major damage by lightning surge is disconnection and malfunction of facilities. It is necessary, therefore, to make a regulation of inspection and maintenance for lightning protection facilities. This paper deals with main issues of a regulation draft of inspection and maintenance for lightning protection facilities based on IEC 62305

  • Social infrastructure facilities such as production, transportation, gas and electricity facilities may experience poor performance depending on time, load, temperature, etc. and may require maintenance, repair and management as they are used. In particular, in the case of transformers, the process of managing them for the purpose of preventing them from failing is necessary because a failure can cause enormous social damage. The management of transformers should consider both technical and economic aspects and strategic aspects at the same time. Thus, it applies the Asset Management concept, which is widely used in the financial industry as an advanced method of transformer management techniques worldwide. In this paper, the operation and power outage data were secured for the asset management of the transformer for distribution, and the asset status was analyzed. Analysis of asset status using actual operation and power outage data is essential for assessing the statistical life and failure rate of the facility. Through this paper, the status of transformer assets for arbitrary A group distribution was analyzed, and the end of life and replacement life were calculated.

  • This paper is about the economic analysis of the replacement of electric facilities in the production facilities. As the interest of energy is increasing, the efficiency of facilities become more important. So, in this paper, we diagnosed facilities, especially electric motors, in the plant and calculated the operating efficiency, power loss with the load factor. And when we replace these facilities into high-efficiency motors, we also calculated new energy efficiency, energy loss and economic analysis through capital recovery factor. As a result, we economically proved that using high-efficiency motor is more beneficial than using non-high-efficiency motors in the model process.

  • Traditional folk houses in Yongdong, Gangwon province play important roles in figuring out natural, human, and social value in the past time including housing life. However, according to the introduction of electric or plumbing equipment in housing life styles, many conventional architectures have been changed by installations of new electric or plumbing equipment, convenience facilities, and etc. Therefore, this study aims to make basic data to prepare for standardized installations of the electric or plumbing equipment, and convenience facilities by surveying of the present installation status, such as electric lights, outlets, switches, wiring, pipe laying, or monitoring devices for crime, disaster prevention facilities, and home appliances etc. Additionally, this paper is related to the meaning and usage, which are connected with the electric or plumbing equipment installations of the traditional folk houses to be prepare for the proper solutions between preservations of the original form and convenient lives for residents.

  • In this paper, we introduce the design and implementation of Information exchange technique among power system facilities and/or their monitoring systems based on Universal Description, Discovery and Integration Service and Simple Object Access Protocol. The rapid progresses in high speed network, 4G web language S/W and embedded H/W enabled faster and easier communications among electric power systems monitoring facilities. However, each facility or system has its own specific protocol like RS-232 and RS-486, which somewhat limits the capability of flexible information exchange among thor In this paper, we try to demonstrate the potential of utilizing the SOAP and UDDI services in exchanging the metadata and possibly high abstraction level informations among electric power facilities and/or their monitoring systems.
