Based on the past design data for electric power load and method of calculation, it is known that in general electric power load has been estimated excessively. For the accurate calculation, it is important to reflect in estimation of a total load capacity and the rated capacities of mechanical pump to be installed in buildings and motor to be actually provided. Various data for electric machine load have been published by Rules for electrical indoor installation, Korea Housing Corporation, KEPCO, Institute of construction technology, and NEC. However, these are very common standard data and far from power capacities actually utilized. As allowance rate of motor and its efficiency is getting improved, load capacities are expected to be lessen. This study has been focused on the selection of optimal electric machine load, which makes a lot of portions of load in the building.

건축물이 다변화와 첨단화를 이루는데 반하여 이들 심장부인 변전실의 크기 결정이 합리적이고 효율적으로 이루어지지 않고 있어 증설 및 부하급변에 대응하지 못하고 있는 실정이다. 적절치 못한 결정은 건물의 기능을 제대로 할 수 없는 중대사인데도 불구하고 선정요건을 고려시 순번의 맨 마지막에 공간을 확보하는 경우가 있어 이의 합리적이고 효율적인 대책이 시급하다. 이를 위해 사례분석을 통한 제 요소를 분석하여 그 대책을 강구한다. As the new large buildings are continuously being built with the advanced technology and skills, an adequate size of electric room needs to be obtained so that engineers establish an efficient and reliable system in the electric room. Considering the current capacity, its expansion and its connecting system, the final size of it should be determined in order to bring an effective use of the building. Therefore, it is important to have the exact method of calculating the effective size of electric room, the heart of the building, especially when the value of land price is very high. In addition, it should be calculated in an accurate way due to the diversification of the system and the compact size of the electricity equipment. However, the research on this area and the comparison and evaluation of the size after construction have not been made enough and the results of them have not been applied when calculating a new size of electric room. Accordingly, this study examines three methods prescribed in the standards of electricity installation technology through case analysis and suggests substantial data by system, capacity, and purpose.

최근 조명기기에서는 소형 경량화 및 고효율에 초점이 모아지고 있으며 이로 인한 전자식 반도체소자의 사용이 급증하고 있다. 이에 따라 조명기기의 안정기 부문에도 전자파 문제가 대두되고 있으며 이에 대한 대책이 절실히 요구되고 있다. 국내의 안정기에 대한 전자파 측정을 해야 되는 범위는 잡음 단자전압 주파수는 150[㎑]∼30[㎒]이고 잡음전계강도 주파수 범위는 30[㎒]∼1[㎓]로 규제하고 있다. 현재 사용되고 있는 안정기는 자기식 안정기(권선형 안정기)와 전자식 안정기로 전자식 안정기는 자기식 안정기에 비해 엄청난 에너지 절약 효과를 가져오지만 신뢰성이 떨어진다. 또한 스위칭 디바이스를 이용하여 주파수를 높여 사용하므로 이에 따른 전자파장해 및 고조파가 발생하는 문제가 발생한다. 전자파장해는 기기의 오동작을 유발하여 기기의 품질저하 및 설비손상, 생산효율 저하 등의 문제를 발생시키며, 주위의 다른 기기에 장해를 주고 있다. 이에 대한 대책으로 본 논문에서는 FLR32SS 1등용 전자식안정기의 전자파(잡음 전계강도 및 잡음 단자전압)를 측정하여 전기용품기술기준 부속서 3에 규정한 EMI(Electormagnetic Interference)측정과 대책 기술에 대하여 연구하고자 한다. Requirements for high-efficiency equipment for energy saving are rapidly increasing recently keeping pace with development of digital and semiconductor technology. Accordingly, there are many changes and development in ballast. Ballast currently in use are Magnetic ballast (Coiled Type) and Electronic ballast. Electronic ballast produces incredible energy saving effect, but falls short of confidence instead. In addition, use at higher frequency through switching device creates Electromagnetic Interference (EMI) and high frequency. EMI creates low quality of equipment, damage in facilities and low productivity by leading miss operation of equipment, and interferes with surrounding machines. In this analysis I am going to examine characteristics of EMI on the Electronic ballast of FLR32SS on type pursuant to annex 3 of Electric Goods Technology Standard, and counter technology.

The most ideal light source that has been adapted to man is sunlight, and thought about a time sunlight in a dark place a lightness necessary us. It becomes an edge that an artificial light source makes the light source that approached a sunlight in final most. However, hard for using the sunlight because of a wide area and space need. Therefore, the light source that considered the characteristic light source use local and a color rendering, a life, the efficiency is developed. I analyze a light characteristic about Neodymium Lamp in this paper, and High efficiency recognizes a possible way
