Incase of not considered seismic design at transformer vault which is made of many informant electrical facility, facility is damaged, electrical fire breaks out and second damage is able to break out at generating earthquake. But seismic design yet is not applied to at transformer vault in the country. Regard to seismic design method of electrical facility installed in the building internal, we present the seismic design of electrical facility using "Building construction design standard" in internal and "Manual of seismic design and construction for Building Electrical facility" in japan. This paper will be used detail seismic design of pipe and facility. reliability inspection plan for seismic design and construction of electrical facility

In modern times, threat of high power electromagnetic wave is increasing. When the electrical grid and communication network are attacked by these high power electromagnetic wave, the whole infrastructure is paralyzed. To protect the infrastructure from these high power electromagnetic wave threat, the shielding facility that can block high power electromagnetic wave is constructed. Also shielding effectiveness evaluation about the constructed facility is important. But, because of space efficiency and saving of construction cost to construct the actual shielding facility, the shielding room wall is generally adjacent to exterior concrete structures. As space between shielding facility wall and concrete structures is very small, arranging the transmitting antenna exterior shielding facility is realistically difficult. Therefore, in this research, The shielding effectiveness measurement plan in the state of exterior narrow space of HEMP shielding facility is presented. And to apply this plan, The influence of shielding effectiveness according to the size of the shielding facility is analyzed.

Appropriate explosion proof electrical equipment should be installed in hazardous areas. In areas where hydrogen is handled, explosion proof electrical equipment adjacent to the hydrogen handing facility must be reviewed for selection of gas group IIC (or IIB+H₂) equipment. When selecting explosion proof electrical equipment for the flammable substance handling facility in areas where hydrogen and flammable substance are handled, the method to avoid gas group IIC (or IIB+H₂) equipment has been suggested by using the operating pressure of the hydrogen handling facility. When the operating pressure of the outdoor hydrogen handling facility is 1.065 MPa or less, it has been confirmed that there is no need to install gas group IIC (or IIB+H₂) equipment for the flammable substance handling facility adjacent to the hydrogen handling facility. And the method of selecting explosion proof electrical equipment for the flammable substance handling facility has been suggested as a flowchart, so it will be able to be utilized when selecting appropriate explosion proof electrical equipment.

School electricity facility is different to general electricity facility because use of immature students. But it was design, construct, manage of general electricity facility law realistically In this study, investigate the recent electrical accident data of school and the present status of electricity facility in Chonan. And grope for future directions of school electricity facility.

In the case of that not considered seismic design at transformer vault which is equipped with many important electrical facilities, the facility is damaged, electrical fire breaks out and another damage may be caused due to earthquake. But seismic design has not yet applied to transformer vault in the country. Regard to seismic design method of electrical facility installed inside the building, the seismic design procedures for electrical facility is presented in this parer, which has been developed by referring "Building design standard" of domestic code and "Manual of seismic design and construction for building electrical facility" in japan. This paper may help engineers perform detail seismic design, construction and reliability inspection of electrical pipes and facilities.

This paper describes the safety assessment algorithm applied for the underground electrical utilities submerged due to flooding. In implementing the algorithm, several factors pertaining to utility safety were introduced into the process flow, and safety weight was given to each factor. It is considered that this algorithm can ensure the safety of electrical utilities installed underground when they are submerged.

In this paper, it is proposed the the SCADA(Supervisory control and Data Acquisition) system in Apartment complex. The proposed SCADA system make use of the computer CRT(Cathod RAy Tube), which automatically observe the Electrical Facility, Elvator Facility, Fire Alarm Facility and process in the real-time data. In order to improve the hardware performance and the information process, the SCADA system composed of master-slave topology and decentralized the supervisory Facility. This system is expected the retrenchment of construction expenditure and the level-up of supervisory execution.

Recently life and properties damage at Japan and China by generating earthquake. So earthquake generation trend and damage in the earthquake risk, and these are a growing interest in domestic. This paper analyzes domestic site and problems of earthquake measures for electrical facility at transformer vault which supply the power the emergence situation at generating earthquake. Also we present the seismic design of electrical facility using "Building construction design standard" in internal and "Manual of seismic design and construction for Building Electrical facility" in japan. This paper will be used detail seismic design of pipe and facility, reliability inspection plan for seismic design and construction of electrical facility.

It is focused on a methodology to establish a optimal inspection cycle of electrical facility of railroad Decision method of optimal inspection cycle is a process which establishes maintenance plan for facilities' immanent function as using reliability theory in operation term In order to ensure normal operation in a given condition, the decision method is logical for selecting effective maintenance plan to consider characteristic of system In estimation of failure rate, critical facility is selected firstly. After that, proper distribution function on each facility is decided to investigate distribution function for extraction of failure rate. Next, cost produced by the case that facility's failure is occurred is surveyed. Finally, maintenance method developed until now is investigated, before suitable model for the facility applying maintenance method is developed, and that maintenance decision is made. Therefore, this process is the method to find optimal inspection cycle for reasonable cost and effective reliability on facility.

In this paper, We studied about effects of human safety due to leakage current on the point of cable connection for outdoor electrical facility in the submerged condition and conducted its evaluation in the testing field. In this case, the reason of leakage on the point of cable connection is caused by formation of electrical pass between the grounded outdoor electrical facility and the enclosure of electrical facility which is connected to grounding system.
