This paper presents the reasonable method for electric power management through efficient use of electricity. With a rapid of national economics and living standard, electrical energy consumption markedly increased. Especially it is increased electrical energy consumption in commercial buildings and thus an energy conservation through efficient use of electricity became more important.

In order to introduce remote monitoring system for effective safety management of electrical facilities for general use, which the most of electrical fires and non-inspection problems due to absence are generated development of local device model considering cost and installation is requested. This paper presents local device models for remote electrical safety inspection of electrical facilities for general use and in order to rational model according to installation place of electrical facilities for general use, compare and analysis cost, installation and communication method of local device models. The results show that rational model for remote safety inspection of electrical facilities located in houses, which occupy the must of electrical facilities for general use, is to give safety monitoring ability to low voltage remote meter reading(or automatic meter reading: AMR).

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

This paper describes the investigation on the spot in relation to electrical safety of electrical installation in elementary middle high school. The investigation was carried out for power receiving system, classroom, chemistry room, music hall and so on. The investigation on the spot was performed by researcher, the related expert, engineer with over fifteen years of industry experience all over the country. As a result of investigation on the spot to 41 schools, common grounding methods at power receiving system were dominant. The risk factors include absence of control box of electric fan, non-installation of earth leakage circuit breaker to power source of experiment stand, use of non-grounding outlet.

An electrical fault is defined as any abnormal condition caused by reduction in the insulation strength between energized conduction parts and ground or any grounded part of an electrical system. Failure of solid insulation can be caused by excessive mechanical tension being applied on the insulation, harsh service environment, aging, and also by corona phenomena. The number of empty houses during normal working hours is rising. As a result, the number of uninspected electric installation for general use is increasing. To define the potential risk of the electric installation, measurement of leakage current has been getting considered, but because the measured leakage current value also contained leakage current by capacitance, the measured value can not be adapted to absolute reference to the installation. Therefore, in this paper, the correlation between the condition of electric installation and leakage current were analyzed.

A conductor has been produced according to IEC standard and low voltage electrical facility has been installed according to IEC 60364. But because of many related and varied standards, it is difficult to apply to design and inspect for electrical equipment. We researched the necessity of design guide which is detailed and systematization from survey. For detailed design guide, we suggest application method and review items at calculations for voltage drop calculations on low voltage feeder by IEC 60364, BS 7671 standard and Consumer's Electrical Installation Guide.

This paper presents the protection effect of SPDs according to installation conditions. To develop the effective protection countermeasures of information and communication equipments against lightning surges, actual-sized experiments in relation to the protection effects on the installation positions of surge protective devices(SPDs), the length of branch circuit the materials and long of conduit were conducted. The best method for protecting the electronic equipments from surges is to install the SPD at the front point of the devices to be protected. The installation method of the metal conduit bonded with common ground conductor were more effective than that of the PVC conduit.
