Human Injury

An objective to develop a labor protection engineering stand was set forth as part of the research and development work "Carrying out theoretical and experimental investigations and development of stands for demonstrating the danger of electric shock at a training ground" for visually demonstrating the danger of injuring a person by touch and step voltages in 3…35 kV medium voltage electric networks. The technical solutions for practically implementing the stand were adopted based on an analysis of regulatory documents, conditions under which dangerous touch and step voltages occur, the most typical human injury cases, and calculation results. Specialists of the National Research University Moscow Power Engineering Institute Department of High Voltage Engineering and Electrophysics, working jointly with specialists of PJSC Rosseti Moscow Region have developed, manufactured, tested, and put into operation a stand for demonstrating human injury by the touch and step voltages when a 10 kV wire falls on the ground, on a car, and when a fault of a live wire on the overhead line support occurs. With the stand having been put in use at the PJSC Rosseti Moscow Region Training Center Ground, this will allow the staff to form a clear understanding of the electric shock danger, to focus on the effects caused by voltage and current, and thereby significantly reduce electrical injuries.

The choice of optimum cross section for overhead line by economic intervals' methodIn this paper an approach to choosing the optimum cross section for overhead line in conditions of incomplete and uncertain information is considered. The two methods of such choice are presented: method of economic current density and economic intervals' method. The correction of the economic intervals method is offered under market conditions of costs. As example 20 kV and 110 kV overhead lines with aluminum, copper and ferroaluminum wires are selected. Universal nomograms with different standard cross section are calculated and constructed. The graphics using Mathcad software are offered.
