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.

Oriented Approach

The Gujarat Narmada Valley Fertilizers Company Ltd (GNFC), a giant fertilizers and chemicals complex, owns the world's largest single stream ammonia and urea plants, and is located in the predominantly backward area of Bharuch District in Gujarat State, India. The company began commercial production on 1st July 1982. GNFC's performance as regards both capacity utilization and pollution control, has been good right from commissioning. Concerning pollution control, the company has adopted a productivity oriented approach which is entirely different from the usual ‘policeman' approach or ‘problem' approach. The company decided to find applications for each of the pollutants. Regarding liquid effluents, the company has successfully concluded a number of research and development projects as a result of which nearly 71% of the total volume of liquid effluent is put to productive use. This has helped the company to reduce the fresh water intake by about 18,000 m3/day (much more than the total volume of fresh water required by the whole of Bharuch city!). The remaining volume (29%) leaving GNFC premises completely conforms to irrigation standards and has been utilized by farmers for the last 5 years. This has resulted in a ‘mini green revolution' in the water-scarce area of Bharuch District. Since the entire effluent is either being recycled within the company or being used by farmers, the company has reached a stage of ‘zero effluent'. The company has also saved more than US$ 500,000 to date, by properly managing liquid effluent.
