Electrical Injuries

Technogenic development of society has caused widespread use in the system «man – production environment» and the system «man – household environment» of household electrical equipment, industrial electrical installations. Failure to comply with the regulated rules of electrical safety of electric current leads to electrical injuries. Designs of electrical installations, equipment, electrical protective measures are constantly being improved. But the level of electrical injuries in Ukraine and abroad tends to increase. This leads to social and economic losses as a result of economic costs in accidents, employee deaths, loss of working time and so on. The most objective indicator of injury is fatal. Thus, the level of fatal injuries at work per 1,000 workers in the developed world compared to the same rate in Ukraine in the UK is 10 times less, in Japan 7 times less, in the US 3 times less. This situation requires analysis and development of appropriate measures to reduce the level of electrical injuries. The analysis of statistical data revealed that the highest level of electrical injuries is observed in the following areas: - in agriculture; - service sector; - in public utilities; - in everyday life. At the same time, the tendency of its growth in the non-productive sphere and the household sector is expressed. So, at present in the general list of accidents from action of an electric current household electric injuries make the largest part – more than 46%. This is due to the insufficient level of education of the population on electrical safety, operation of electrical equipment in high-risk areas or in particularly dangerous by the degree of electric shock. At the same time, the level of domestic electrical injuries is higher in rural than in urban areas. It was also found that the greatest danger is posed by mobile and portable electrical installations, power tools and internal wiring. In addition, the housing of such electrical installations is often grounded through one of the cores of the power cable, which is unacceptable. The reasons for the high level of electrical injuries also include non-compliance with regulated organizational measures to ensure occupational safety and the so-called «human» factor. To improve the situation, it is necessary to intensify and increase the level of training of the population and employees on electrical safety, development and application of more modern switching electrical protection.

Insight Into

Unfired combined-cycle power plants of Siemens/KWU design each comprise five different package-engineered functional areas of mechanical and associated electrical equipment which are matched to different fuels, site conditions and operating requirements in order to achieve optimum power generation with each application. A modular programmable microprocessor-based automation station allocated to each functional area sequentially controls and protects all the equipment therein. By means of a redundant bus system all the functionally distributed automation stations are connected to one another and to a central control room where VDU screens provide operators with an in-depth insight into the running performance status of the entire combined-cycle block at all times. Function keyboards and back-up conventional hardwired controls permit operators to intervene in the automatic operation of the station whenever desired.

Risk Rating

The industrial development and the increase in the use of fossil fuels have been accelerating global warming and climate change, thereby causing more frequent and intense natural disasters than ever before. Since electrical facilities are generally installed outdoors, they are greatly affected by natural disasters, thus accidents related to electrical equipment has been on the rise. In this paper, we present the risk rating associated with climate change by analyzing the statistics of electrical fires, electric shock accidents and electrical equipment accidents caused by domestic climate change. Further, we present a risk rating analysis model for electrical fires on a monthly basis through the data analysis of electrical hazards associated with various regional (metropolitan city) climatic conditions (temperature, humidity), and analyze the accident risk rating for natural disasters related to low and high voltage equipment. Through this risk analysis model for each region and type of equipment, we presented a basic prediction model for electrical hazards. Therefore, it is possible to provide electrical safety services in the future by displaying a risk prediction map of electrical hazards for each region and type of electrical equipment through web sites or smart phone apps using the presented analysis data. Further, efforts should be made to increase the robustness or reliability of electrical equipment in order to prevent electrical accidents caused by natural disasters due to climate change in advance.

In this article, we consider the modes of neutrals of 0,38 to 750 kV networks. In any network with different voltage classes, the neutral point of a power transformer winding can operate both in isolated and deaf earthed mode. However, the choice of this mode depends on economic feasibility. The paper presents arguments and advantages of application of system with isolated and compensated neutral of networks with voltage classes 6–35 kV. For networks of these voltage classes various options of connecting arc suppression reactors with step and smooth regulation, as well as low and high impedance resistors in the neutral point of neutralizing transformer or zero sequence filter are considered. On the example of operation of electric networks of the Republic of Chuvashia for many decades it is emphasized that compensation of capacitive currents with arc suppression reactors is an effective and reliable way to protect not only substation electrical equipment from overvoltage, but also to ensure electrical safety of people and animals, as well as reinforced concrete towers from destruction. It is noted that the 6–35 kV networks in the future can be made with deaf earthed neutral. However, this will be possible under the condition that self-supporting insulated wires will be installed on overhead transmission lines instead of bare wires, and cross-linked polyethylene cables will be used on cable lines. It is emphasized that the introduction of work under voltage in 6-35 kV networks and digitalization of substations with the widespread introduction of microprocessor technology will accelerate the transition from a system with insulated (or compensated) neutral to a deaf earthed system. Nevertheless, the decision to switch from the insulated neutral system to a deaf earthed system will remain the prerogative of the design organization based on the specifics of the electrical equipment and the sphere of industrial activity.
