[IEV number 421-01-14]Oil transformers
The magnetic circuit and the windings are immersed in a liquid dielectric that provides insulation and evacuates the heat losses of the transformer.
This liquid expands according to the load and the ambient temperature. PCBs and TCBs are now prohibited and mineral oil is generally used. It is flammable and requires protective measures against the risks of fire, explosion and pollution.
The most commonly used protective measures are the DGPT or the DGPT2: Gas, Pressure and Temperature sensor with 1 or 2 sensing levels on the temperature. This system cuts off the LV load (1st level) then the HV supply (2nd level) when there is a fault inside the transformer. A holding tank is used to recover all the liquid dielectric.
Of the four types of immersed transformer: free breathing transformers, gas cushion transformers, transformers with expansion tank and transformers with integral filling, only the latter are currently installed.
[Legrand]Масляные трансформаторы
Магнитная система и обмотки трансформатора погружены в жидкий диэлектрик, служащий изоляцией и теплоносителем.
Жидкий диэлектрик изменяет свой объем в соответствии с нагрузкой трансформатора и температурой окружающей среды. Поскольку в настоящее время применение полихлорированных дифенилов и тетрахлорбифенилов запрещено, то в основном используют минеральное масло. Оно огнеопасно, поэтому необходимо принимать меры против возникновения пожара, взрыва и загрязнения окружающей среды.
Как правило, применяются системы DGPT (одноуровневые системы, использующие датчики газа, давления и температуры) или DGPT2 – двухуровневые системы. В случае возникновения аномального состояния трансформатора данные системы отключают нагрузку цепей низшего напряжения (первый уровень защиты), а затем питание обмотки высшего напряжения (второй уровень защиты). Активная часть трансформатора находится в баке и полностью покрыта жидким диэлектриком.
Существует четыре типа масляных трансформаторов: трансформаторы с системой свободного дыхания, трансформаторы с газовой подушкой между зеркалом масла и крышкой трансформатора, трансформаторы с расширительным баком и трансформаторы с гофрированным баком. В настоящее время применяют только трансформаторы последнего типа

hydroelectric energy
The free renewable source of energy provided by falling water that drives the turbines. Hydropower is the most important of the regenerable energy sources because of its highest efficiency at the energy conversion. There are two types of hydroelectric power plants: a) run-of-river power plants for the use of affluent water; b) storage power plants (power stations with reservoir) where the influx can be regulated with the help of a reservoir. Mostly greater differences in altitudes are being used, like mountain creeks. Power stations with reservoirs are generally marked by barrages with earth fill dam or concrete dams. Though hydropower generally can be called environmentally acceptable, there exist also some problems: a) change of groundwater level and fill up of the river bed with rubble. b) Risk of dam breaks. c) Great demand for land space for the reservoir. d) Diminution, but partly also increase of value of recreation areas. As the hydropowers of the world are limited, the world energy demand however is rising, finally the share of hydropower will decrease. (Source: PORT / PHC / PZ)

soil moisture
1) Water stored in soils.
2) One of the most important elements involved in pedological processes and plant growth. There are three basic forms:
a) water adhering in thin films by molecular attraction to the surface of soil particles and not available for plants is termed hygroscopic water.
b) Water forming thicker films and occupying the smaller pore spaces is termed capillary water. Since it is held against the force of gravity it is permanently available for plant growth and it is this type of soil water which contains plant nutrients in solution.
c) Water in excess of hygroscopic and capillary water is termed gravitational water, which is of a transitory nature because it flows away under the influence of gravity. When the excess has drained away the amount of water retained in the soil is termed its field capacity, when some of its pore spaces are still free of water.

A small-scale, simplified, experimental ecosystem, laboratory- or field- based, which may be: a) derived directly from nature (e.g. when samples of pond water are maintained subsequently by the input of artificial light and gas-exchange); or b) built up from axenic cultures (a culture of an organism that consists of one type of organism only, i.e. that is free from any contaminating organism) until the required conditions of organisms and environment are achieved. Also known as microcosm. (Source: ALL2)

trade barrier
An artificial restraint on the free exchange of goods and services between nations. The most common types of trade barriers are tariffs, quotas, and exchange control. Such obstacles to trade are usually imposed by a country that wishes to protect domestic products in their home market against foreign competition, better its terms of trade, reduce domestic unemployment, or improve its balance-of-payments position. The raising of trade barriers by one country often provokes other nations position. Generally, the effect of a trade barrier is to reduce the volume of trade while increasing the domestic price of the protected good. Thus, it results in a relatively inefficient allocation of world resources and reduces the level of total world income and production. (Source: GREENW)

sea circulation
Large-scale horizontal water motion within an ocean. The way energy from the sun, stored in the sea, is transported around the world. The currents explain, for example, why the UK has ice-free ports in winter, while St. Petersburg, at the same latitude as the Shetland Islands, needs ice breakers. Evidence is growing that the world's ocean circulation was very different during the last ice age and has changed several times in the distant past, with dramatic effects on climate. The oceans are vital as storehouses, as they absorb more than half the sun's heat reaching the earth. This heat, which is primarily absorbed near the equator is carried around the world and released elsewhere, creating currents which last up to 1.000 years. As the Earth rotates and the wind acts upon the surface, currents carry warm tropical water to the cooler parts of the world. The strength and direction of the currents are affected by landmasses, bottlenecks through narrow straits, and even the shape of the sea-bed. When the warm water reaches polar regions its heat evaporates into the atmosphere, reducing its temperature and increasing its density. When sea-water freezes it leaves salt behind in the unfrozen water and this cold water sinks into the ocean and begins to flow back to the tropics. Eventually it is heated and begins the cycle all over again. (Source: MGH / WRIGHT)

water taste
Taste in water can be caused by foreign matter, such as organic compounds, inorganic salts or dissolved gases. These materials may come from domestic, agricultural or natural sources. Some substances found naturally in groundwater, while not necessarily harmful, may impart a disagreeable taste or undesirable property to the water. Magnesium sulphate, sodium sulphate, and sodium chloride are but a few of these. Acceptable waters should be free from any objectionable taste at point of use. (Source: CORBIT)

ocean-air interface
The sea and the atmosphere are fluids in contact with one another, but in different energy states - the liquid and the gaseous. The free surface boundary between them inhibits, but by no means totally prevents, exchange of mass and energy between the two. Almost all interchanges across this boundary occur most effectively when turbulent conditions prevail. A roughened sea surface, large differences in properties between the water and the air, or an unstable air column that facilitates the transport of air volumes from sea surface to high in the atmosphere. Both heat and water (vapor) tend to migrate across the boundary in the direction from sea to air. Heat is exchanged by three processes: radiation, conduction, and evaporation. The largest net exchange is through evaporation, the process of transferring water from sea to air by vaporization of the water. (Source: PARCOR)

rising sea level
Sea level rises are a possible consequence of global warming. As the amount of free water in the ocean increases, and as the water becomes warmer, global warming will increase. In addition, according to theory, the heating at the poles may reduce the amount of water trapped in glaciers and ice caps. By the year 3000, the seas could rise between one and two metres. Such an event would clearly threaten low-lying areas, particularly in Asia, where million of people live and farm on river deltas and flood plains. (Source: WRIGHT)
