Generators-Primary Cooling Water Circuit functioning : In order to distinguish the treated water from the secondary coolant (raw water, condensator etc.) it is named as primary water because it is used for cooling stator winding, phase connectors and bushings . The secondary cooling absorbs the heat from the primary cooler when water is circulated in a closed circuit by the primary water cooler. The pump is supplied with in primary water cooler. Water is supplied to the flow paths of the generator
developing so they can be used only in a few countries. There are many reasons we are looking towards alternative energy sources. With many countries, and US cities, signing the Kyoto Treaty, efforts to reduce pollutants and greenhouse gases are a primary focus in today's culture. Alternative, or renewable energy, sources show significant promise in helping to reduce the amount of toxins that are by-products of energy use. Not only do they protect against harmful by-products, but using alternative
Dear Prime Minister, I believe that New Zealand’s energy supply is secure for the future. From my research, I have found that from 1974 to 2009 the electricity demand has more than doubled in size. Currently, most of New Zealand’s energy is generated from renewable sources which mean that it can be used by future generations to come; we do not need to be concerned that they will cease to exist. However, New Zealand has been named as one of the least energy efficient countries in the world and
Energy Recently, the constraints of reducing fuel consumption and pollution have improved the efforts toward renewable energies. Renewable energy resources such as sunlight, wind and water are eventually unlimited and are much more eco-friendly than fossil fuel. It can be used directly as solar ovens and geothermal heating, or indirectly by creating another form of energy

destruction or manipulation of the tissue. Whereas various energy sources, including electricity, ultrasound, laser, argon gas, microwaves, or radiofrequency (RF) waves, may be used, the fundamental principle involves tissue necrosis and hemostasis by heating. The process of denaturation of tissue begins with the

the development of hydraulic power networks. Numerous scientists like Blaise Pascal and Benedetto Castelli contributed enormously in this regard. 1.2 The Science of Hydraulics The term “hydraulics” is derived from the Greek words “hydro” (meaning water) and “aulics” (meaning pipes). We come across hydraulic machines like cranes, forklifts etc in our day to day lives. Aeroplanes and cars use the concept of hydraulics for carrying out certain operations. A hydraulic system works on the
Up until a few years ago, we used to exploit fossil fuels for almost all of our needs (heating, transportation, etc.) without thinking if there are enough supplies or even about their negative effects their emissions cause to the environment. According to many scientific investigations our fossil fuel resources (oil, coal and gas) are running out, furthermore their emissions pollute the environment and contribute to the greenhouse effect. Undoubtedly, these situations as well as the fact that the
allow charges (electrons) to flow through them easily. E.g. metal Therefore no matter how hard that you rub a metal tap no static charge will build up because the electrons that you are giving the tap just keep on moving up the tap and down the water line until they reach a ground. Insulators do not allow charges to flow through them. The charge builds up on its surface eg. Faraday Cage Both a positive and a negative charge can build up on ____________________ Only ______________ can obtain
