전력사용이 증가함에 따라 전기설비에 의한 전기화재 수가 늘어나고 있다. 통계에 따르면 전기화재가 화재원인 중 가장 많은 비중을 차지하고 있음을 알 수 있다. 그럼에도 불구하고 전기화재를 정확히 찾아낼 수 있는 조사기법이 개발되지 않고 있는 실정이다. 이 논문은 전기화재 원인과 아크차단기의 특성에 관하여 분석한다. 아크에 의한 위험을 수학적 분석을 이용한 전력계산을 통하여 분석하고 단락회로에 의한 위험성과 비교 한다. 또한 아크차단기와 기존의 누전차단기와 비교를 통하여 아크차단기의 필요성을 제기한다.

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.

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.

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, we studied on the electrical safety evaluations of transformer insulation cover. In order to take preventive measures against an electric shock disaster in 22.9kV transformer installation, we put the insulation cover on a transformer charging parts. It needs to be designed so that the insulation covers have superior properties such as, arc-resistance, weather-resistance and heat-resistance, because they are used until the damage and destruction occur. To establish the protection cover to reduce the electrical shock, we analyzed damage mechanism and risk factors which happened by structural fault of an insulation cover in this paper. Also, based on the experimental results, we are planing to suggest new improved insulation cover models.

In this paper, the oxidization characteristics were analyzed according to the shapes of Residual Current Protective Device(RCD) contacts. RCD is an electrical safety device specially designed to immediately switch the electricity off when electric leakage is detected at a level harmful to a person using electrical equipment. The shapes of RCD contacts are a little bit different according to the models. When RCD is turned on, stationary and moving contact do not fit together. So, it can cause the increase of contact resistance. To discover the deterioration characteristics of RCD contacts by switching repetition, the contacts were analyzed by stereo microscope, Scanning Electron Microscope(SEM) and Energy Dispersive X-ray Spectrometer(EDS).

To analyze risk factors of temporary power installations, the investigation was carried out for power receiving system and pack and panel boards at construction sites. The subject was variable such as an airport, an apartment, a municipal playground. There are many risk factors caused by inadequate working environments and the deterioration of temporary power installations using equipment with minimum safety devices at construction sites. There, it is intended to present problems and preventive measures against electrical shock accidents, through analyzing risk factors of real field condition and investigating temporary power installations all over the country.

Electrical product safety certification is for public safety. Korea electrical safety certification (KC) is being tested and certified on the base of Korean electrical appliance safety act and KC scheme. There are operating system and Electrical safety standards in the KC scheme. KC' operating system was adapted from japan operating system of Japan certification scheme. But KC certification' electrical safety standard was adapted from IEC standards of IECEE CB scheme. So There are many problems such as difference of version between KC standards and IEC standards, discrepancy between operating system and standards. Therefore, This paper analyzed the reason of discrepancy and proposed the improved KC certification operating system in order to reduce cost and to save time in the procedure of issuing KC approval for public safety in using electrical products and also for global competence.

A person's body resistance in the waterpark, public bath and similar places is lower than any other places due to effect of water. So low voltage may create a shock hazard for the human body in case of leakage or fault currents from lighting unit etc. We researched the related regulations these are internal standards, NEC, IEC and investigated the actual conditions for the prevention of electrical shock due to lighting units in the waterpark, public bath and similar places. So we could present actual facilities's problems and solutions

As the increasing national power crises due to various environmental factor, power market change is needed more developed and systemized DSM(Demand Side Management) search at DR market. To overcome national power crisis outbreaking every year and manage the eletric power reserve ratio, we need to construct and develop the electric safety manager and general public main oriented national power plant. For the advanced national power demand management system, it is required the application development like OpenAPI, Big Data Acquisition, Web/APP basd on ICT.
