  • In this paper, we evaluate safety of grounding system which is designed according to IEC standards. Safety assessment of construction site and grounding system of building is needed before construction for the safety of human in building. Until now, in case of domestic field, design of grounding system is proceeded based on methods which are proposed in IEEE Std. 80. In other words, it is not in the situation that grounding system is designed based on IEC standards. Therefore, we propose a method which designs grounding system and evaluates safety of it according to IEC standards. We measure ground resistance of construction site using measuring equipment of ground resistance. Using this value, soil structure and ground resistivity are obtained through program analysis. CDEGS program of SES company is used for simulation analysis.

  • In recent years, equipment and network standards have been increasing in both number and complexity. Two standards that will soon be introduced to KOREA are the HV standards for assessing distorting and fluctuating loads, IEC 61000-3-6. Utility engineers, being under increasing time constraints, are turning more and more to software to quickly solve problems. This paper describes the methodology used to implement the above standards in Microsoft Excel in order to assist utility engineers to readily apply these standards in practical situations.

  • 유희용전차는 유원시설 내에 설치된 놀이기구의 일종으로 산자부고시인 전기설비기술기준 제252조에서 별도로 규정하고 있다. 전기설비기술기준은 법적 최소요건으로 일본의 전기설비기술기준령을 토대로 제정된 이후 기술적 환경의 변화에 신속하게 대응하지 못함에 따라 유희용전차의 시설에 관한 규정에 있어서도 현실적인 문제점이 많이 내포되어 있다. 따라서, 본 논문에서는 이와 같은 현장 적용상의 기술적 문제점을 해결하기 위하여 전국에 있는 28개의 유희용전차를 대상으로 현장 적용실태 분석 및 실측을 통하여 현행 전기설비기술기준의 개선방안을 제시하였다.

  • The necessity of Power Quality(PQ) Management grow bigger because the disturbance strength in power system is increasing, on the other hand, the tolerance of electrical components is reducing with widely use of the IT and digital equipments. The domestic management standards on power quality are enacted based on the IEC standards in recent. Since the IEC standards defines the measurement and evaluation point on PQ as PCC(Point of Common Coupling) which is normally the point of penetration between customer and power company, the PQ monitoring system(PQMS) should be made to measure and manage the PQ of custom effectively. In this paper, therefore, the economical construction plan on PQMS using the wireless communication channel in distribution automation system is suggested, and the usefulness of the PQMS are shown by analyzing the PQM data with IEC standards.

  • Overhead transmission lines in domestic area have been built by several different design standards of dip and ground clearance. This paper describes an experimental study for evaluating load capacity and dip margin in overhead transmission lines. Such design standards for selection of overhead transmission conductors, dip and ground clearance, as well as electrical equipment technical standard are discussed. Based on daily load and weather data, several characteristics such as line utilization factor, load factor, conductor temperature and dip, etc. are analyzed, and compared with the specified levels of design standards. As a result, it is verified that DLR method can be a clue of the solving of the problem, for occurring in old transmission conductors which may be rarely operating below standards.

  • The safety and reliability of the power system short-circuit current, the short-circuit current depends on the failure to obtain the objective is to quickly eliminate the breaking capacity of the circuit-breaker selection of the cable, the insulation of electrical equipment and protective relay an important factor in determining the level correction and protective relay selection scheme to be meaningful. Standards used in the domestic circuit breaker is applied to the production of IEC standard, but the American National Standards (ANSI / IEEE) by NEMA specification of the fault current calculations and the application of the asymmetric coefficient Korea. Therefore, in this paper, the IEC 60909 standard IEC breaker fault current calculation method and the method for selection of system configurations reviewed and protection system for reviewing the configuration of various protective relays appropriate correction and the correction value is main protection, back-up protection the equipment so that the period of protection relay coordination to minimize accidents and accident protection to minimize interruptions proposed for cooperation.

  • The speciality of education installation has to be applied to the design construction, inspection of school in the installation. But. it was applied general electric installation standards in korea. Therefore, the electric shock accidents and fire was more frequently occurred in the school than in other building. So, this paper, is proposed the comprehensive countermeasure for safety of school electric installation
