  • XLPE insulated power cables are introduced in Korea in 1980s. The cable installation test has been carried out according to the Korean Technical Reference of Electrical Facilities. But recent research results shows DC Hipot test cannot detect the serious defects in XLPE insulated cables. VLF test is recommended as a installation test of XLPE insulated cables by CENELEC and IEEE standards in 1996 and 2001 respectively. We suggest to apply VLF test as an installation test for XLPE insulated MV cables in Korea.

  • ISO 9000 is a series of several standards(ISO 8402, 9000, 9001, 9002, 9003, 9004,...). ISO 9000 is a standard explaining fundamental concepts, defining important terms, and providing guidance for selecting among the other standards. ISO 9001, the most comprehensive standard to ensure quality in design, development, production, installation, and servicing. ISO 9002 is used to assure conformance to specification, installation and servicing. ISO 9003 has the least requirement among three standards and applies to inspection and final testing. ISO 9004 is a standard developed for internal use only and not applicabe to contractual arrangements. In this paper, quality system requirements for ISO 9000 series are also specified.

  • Purpose: Picture Archiving and Communication System (PACS) is difficult to implement in the best of situations, but evidence is growing that the benefits are significant. The aims of this study are to analyze the current status of full PACS and establish successful installation standard of dental PACS. Materials and Methods : Materials and methods were based on the investigation of current working status and installation standard of PACS, and observation of variable issues to installation of dental PACS. Results: By September 30,2004, full PACS implementations in their facilities were 88.1 % in specialized general hospitals (37 installations out of total 42 hospitals), 59.8% in general hospitals (144 installations out of total 241 hospitals), 12.3% in medical hospitals (116 installations out of total 941 hospitals) and 3.6% in dental hospitals (4 installations out of total 11 0 hospitals) Only 4 university dental hospitals currently have installed and are operating full PACS. Major obstacle to wide spread of dental PACS is initial high investments. Conclusions: Clinical environments of dental PACS differed from medical situation. Because of characteristic dental practice, the initial investments for dental PACS are generally much greater than those of medical PACS. Also new economic crisis makes users scruple. The best way to overcome these limitations is to establish an economic installation standard for dental PACS. Also the clear technical communication between the customer and the supplier before both sides are committed to the obstacles are critical to its success.

  • It's a general tendency that electrical facilities of power station become a large size and increase in number because electrical facilities become big and complicated with internal industrial development and economic growth. So, electrical accidents were increased in this electrical facilities of power station. Therefore, in this paper we compared domestic and foreign standard on safety environment of power station. From this, we draw several questions in case of installation on power station and we proposed a draft of relative standard to apply in power station.

  • This research surveys actual conditions on lighting environments of the elderly's houses. from the results of survey on actual conditions of lighting in the elderly's houses, they don't meet standard of illumination suggested by KS A 3011, and, standard of ovarall illumination is satisfied in general, but illumination in a side of work or other activities is lower than the standard and it has failed to suggest standard that is considering user's characteristics, visual characteristics going with their ages and so forth, it is thought to urgently prepare standard which considers visual characteristics of the elderly and their ages.

  • Traffic Safety and efficient Road Traffic Policy of Traffic management came into effect over the certain size of the road like main road. Comparatively, Safety for Living street is deteriorated. Especially, Vehicle are usually priority to the life-zone street, even though Safety for the Passengers are essential to the life-zone street in the residential area. Improvement for the Living street has not been achieved In this study, To suggest Intersection Notifications standard of installation in Living Street, We execute on-site survey in priority to Gwangju Metropolitan City. Furthermore, After We suggest experimental value for the Intersection Notifications' standard of installation Prediction model in the Living street, Intersection Notifications compare & veritfy experimental value to the installation point's value to suggest the standard of installation in the living street. As a result, We can prevent frequent traffic accident in the Living Street. Furthermore, We are judged by installation of intersection Notifications considering stability and convenience to the passengers who are using the living street.

  • This paper discusses one overall reactive power installation pattern that will satisfy system performance constraints for base case. The cost of installation is minimized, Existing controllers are fully utilized prior to any addition of new installation. Installation pattern for the required new shunt compensation is comprised of discrete, standard size components.

  • Owing to WTO/TBT, Many countries are trying to accord their own various national codes and standards with international standards. Also Korean electric power code is being made consistent with the new standards which include the international standards. The new code will affect the many aspects of building construction. In order to cope with the change of the electric power code, this paper analyzed the trend of the international standard(IEC 60364, IEC 61024) and we think this study will help engineers to understand the international electrical standards.
