Electrical leakage happens when faults in electrical apparatus or power lines occur. It causes electrical fires and electric shocks. In order to reduce accidents caused by electrical leakage current, it is important to detect faults effectively and shut off the power. In this paper, firstly we analyzed statistics of electrical fires and electric shocks caused by electrical leakage current. Secondly, standards of allowable leakage current and body impedance models were analyzed. Lastly, effective application methods for breaking electrical leakage current were suggested. The results will provide useful preventive measures of electrical fires and electric shocks caused by electrical leakage.

This paper presents a quantitative analysis method to quantitatively indicate a electrical fire preventive effect of safety inspection for electrical facilities for general use. Logic model was developed based on whether enforcement of safety inspection for electrical facilities, and then the developed analysis model was converted to hydraulic model by using mathematical logic. The electrical fire preventive effect of safety inspection for electrical facilities was quantitatively calculated by applying electrical safety inspection results and fire statistics for five years to the developed hydraulic model. The results show that electrical fire preventive effects of 5,542 cases on annual average for five years.

Korea Electrical Safety Cooperation(KESCO) have provided the electrical safety speed-call service from 2007 year. Purpose of the service is to reduce discomfort of electricity use and to prevent electrical accident like as electrical fire and shock accident by providing emergency treatment service on fault of the residential electrical facilities notified in the specific house like as a lower-income group and a social welfare facility. But efficiency and economic evaluation of the electrical safety speed-call service is impossible because analysis on the quantitative effect of the service is difficult. This paper presents cost-benefit analysis method and result of the electrical safety speed-call service. The presented cost-benefit analysis method has a two-step process: the first step is to measure quantitative electrical fire prevention effect of the service by using electrical accident statistics and developing outcome analysis logic model of the service effect, and the second step is to analysis cost-benefit(B/C)of the service by calculating quantitative benefit analysis on the measured quantitative electrical fire prevention effect. The results showed that cost-benefit(B/C)of the electrical safety speed-call service is over 4 after 2010 year.

A roadmap for Electrical Safety Technology has been designed based on the study that has been contributed by the specialists, professors and researchers in electral safety field. The roadmap is divided into five major fields including, for instance, the electrical fire accidents roadmap. The other four roadmaps are for electrical shock accidents, electrical facilities accidents, electrical safety policies and electrical safety culture-education, respectively. Each roadmap has a purpose, a scope, and a technical characteristic. Following the roadmaps can result in significant reduction of electrical fire accidents, electrical shock accident victims and so forth. The result can also be utilized in guiding the planning and development of the future electrical safety technology.

It is necessary to study the prevention and the management of electrical facilities because the electrical fault took place at the dust occurrence area due to environmental pollution. In particular, the dust accumulates easily on insulation material which is exposed an external long time. The leakage current brings out electrical fault after all. Also, it is need to variation of material and shape to repress a leakage current on electrical material. In this paper, we measured a leakage current on electrical material of facilities by dust, and in experiments the prevention to electrical fault was studied.

The standard of living has been getting higher by reason of industrialization and economic growth. It makes people have more cultural desire(wants). Because of reasons mentioned above, a number of entertainment place and performance with high-tech is increased. This has been brought also increasing a number of electrical accident such as electrical shock, electrical fires and accidents of electrical facilities. This paper suggests technical, operational and special precautions of actual electric main line systems in entertainment places and is also written on the purpose of being applied with related provisions to designing electrical facilities, construction, check-up and inspection and maintenance for preventing further electrical disasters in entertainment places.

An Electrical facilities of fountain is one of the vulnerable facilities because it is exposed to water. Especially, some children enter the fountain and play in the water in the hot season. For example, death from electrical shock in fountain was reported in domestic and foreign papers. In this paper, we analyzed the riskiness of electrical shock on the basis of a fact-finding survey and comparing the domestic and international standard of electrical facilities in fountains.

In this paper, the polymer insulators which had been used for electrical insulation were investigated surface leakage current and deterioration pattern. Because the electrical fault took place at the dust occurrence area due to environmental pollution. In particular, the dust accumulates easily on insulation material which is exposed an external long time. The leakage current brings out electrical fault after all. Also, it is need to variation of material and shape to repress a leakage current on electrical material. In this paper, we measured a leakage current on electrical material of facilities by dust, and in experiments the prevention to electrical fault was studied.

This study proposes to suggest a direction hereafter which is the most suitable operating system of electrical safety management agency for electrical facilities to enhance electrical safety considering our domestic conditions. It was designed to prevent electrical disasters which are increasing due to environmental changes in the electrical industry, and the diversification and complication of the electrical facilities. And the strategy of this research is based on conditions of safety management agency for the electrical facilities, with the analysis on conditions of electrical disasters, and with a questionnaire investigation for owner of electrical facilities, safety management agency. Results of this research are expected to be used to prevent electric fires and shocks effectively by reinforcing the electrical safety management agency of electrical facilities having danger of large-scaled accidents. It is expected to enhance the nation's competing power against foreign countries by reducing the human and physical loss, resulted from the development of reasonable operating system for electrical safety management agency.
