본 논문은 영상화재감지기(Video Fire Detector)의 시험 및 설치기준에 관한 연구로서 FM Approvals, UL, ISO7240 및 NFPA 72 기준들을 서로 비교분석하여 국가화재안전기준 203 (NFSC 203)에 반영되어야 할 기준들을 제안하였다. 영상화재감지기의 시험과 관계된 FM Approvals 기준에는 연기형, 불꽃형으로 분류되고 비화재보시험이 있었으나 UL 기준에는 연기형만 제시되어 있었다. 외국 기준인 ISO 7240에서는 화재현상 검출유형 등 6가지를, NFPA 72에서는 화재현상 검출유형 등 3가지를 조사하였다. CCTV 설치 표준공법에서는 영상화재감지기의 설치기준에 필요한 항목이 15가지가 있었으며 설치방법에 따라 각 분야별 기준이 제시되어 있었다. 영상화재감지기 적용을 위해서는 감지기 시험항목 중 용어의 정의, 감지기의 구분, 구조 및 기능에 관련항목을 삽입하고 감도조정, 비화재보방지, 주위온도시험, 유효감지거리 및 감도와 시야각, 노화시험, 살수시험, 내화시험의 7개 항목의 적용이 필요하다. 현장 설치를 위해서는 국가화재안전기준 203 (NFSC 203)에 작동환경 및 조도기준을 설정하고 음향장치, 표시등의 설치거리 등의 기준을 삽입하여야 한다.

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.

본 논문에서는 철도 시스템에서 사용하는 저압 전원용 서지보호장치(surge protective devices) 규칙의 성능평가 항목 및 성능개선 방안에 대하여 고찰하였다. 먼저 철도시스템 환경과 관련된 전자기장해(electromagnetic interference) 현상을 검토하였다. 그리고 국제규격인 IEC 및 IEEE와 평가항목 및 펑가방법 등을 비교 검토하였다. 검토 결과 국내 철도관련 규격은 국제규격과 비교하여 비교하여 발견하였다. 개선방안으로 서지 보호소자 단위의 시험은 삭제하고, 규격 종류는 전원용과 신호용으로 분리하며, 서지 파형은 국제적으로 인정된 것을 사용하도록 제안하였다. 철도용 저압 서지보호장치에 대해 서지제한전압 측정 및 서지 수명시험을 국제규격에 따라 시험한 결과 만족스러운 결과를 얻었다.

IEC is an international standards which are used in many countries with Europe as the center. IEC standard is introduced in Korea according to WTO/TBT agreements, however until now there are no buildings in Korea which are designed applying IEC standard. Therefore, KEA(Korea Electric Association) is scheduled to construct Korean low voltage electrical installation integration test site which is designed applying IEC standard. In this paper, before being under construction of Korean low voltage electrical installation integration test site, power substation is modeled based on real design parameters and method to select circuit breakers and cables is presented applying IEC standard in the modeled power substation. EMTP(ElctroMagnetic Transient Program) is used for simulation program. EMTP which is power system analysis program is easy to model power system and power substation.

As products using LEDs are developed actively, also there has been large request for LED products that can replace traditional lamps like fluorescent lamps and metal halide lamps. But so far there is no proper standard that manufacturer can use and test it. As a result manufacturer can't develop retrofit LED lamps and sell it even they have technology. In this study, by analyzing control gear for fluorescent lamp that is currently used in market which is magnetic or electronic ballast, I'd like to develop proper test method by investigating compatibility between all-type control gear and LED retrofit products.

Running low of fossil fuel energy forces the industry to find a new way to overcome this energy crisis. One of the solutions is using the unlimited and everlasting energy sources like wind, sun, water, and so on. Especially, sun energy becomes the hottest issue in recent years because of its merit in installation, operation and abundant material source of silicon. In 2008, about 5.5GW photovoltaic (PV) system has been installed all around world. Many professional renewable energy organizations expect that the total PV system installation will be 30GW. To sustain the long-term stability of the PV system, several institutes perform the test based on IEC standards like IEC 61215 for silicon crystalline PV module and IEC 61646 for thin film PV module. Also in South Korea, Korea Institute of Energy Research (KIER) performs the certificate test according to IEC 61215 standards. In this paper, we want to summarize and inform the 3 years‘ test results of domestic and foreign PV modules. The specific and technical explanation will be shown in the following paper in detail.

The photovoltaic (PV) system consists of solar cells, solar modules, inverters and peripherals. The related evaluation and certification are proceeding as standards published by the IEC (International Electrotechnical Commission) TC (Technical Committee) 82. In particular, PV module is a component that requires stable durability over 20 years, and evaluation in various external environments is very important. Currently, IEC 61215-based standards are being tested, but temperature, humidity, wind and solar radiation conditions are not considered in all areas. For this reason, various types of defects may occur depending on the installation area of the same photovoltaic module. In particular, the domestic climate (South Korea) is moderate. The various test methods proposed by IEC 61215 are appropriate, excessive, or insufficient, depending on environmental condition. In this paper, we analyze the climate data collection for one year to understand the vulnerability of this test method of PV modules. Through this, we propose a test method for PV module suitable for domestic climatic conditions and also propose a technical consideration for installation and design of PV system.
