  • Essay / Supply of electrical energy by different energy sources

    For electricity to be produced, it is necessary to have a source of energy. Some of these sources will include wind, liquid water forced to move at high speeds, or steam projected at high pressure. Energy harnessed from these sources is used to operate large turbines which in turn operate connected generators which produce electricity which is extracted and distributed. These sources produce mechanical and kinetic energy which is extracted by massive turbines whose blades rotate at high speed. These blades are connected to the turbine shaft. The turbine shaft is then connected to the generator alternator. The main task of the alternator is to use and absorb the kinetic or mechanical energy produced by the turbine device to create rotational motion and, therefore, produce electricity (OXLADE 2011). The rotation of the turbine shaft in turn causes the internal workings of the generator to rotate. These internal modules work collectively to cause relative movement between the magnetic and electric fields, which in turn generates electricity. The internal modules will include the stator which is the fixed and immobile module which comprises a set of electrical conductors wound into coils on an iron core and the armature which is the poignant module which produces a rotating magnetic field. In the space inside the generator identified above as the stator, there are two polar field magnets that create a magnetic field. These are positioned on either side of the armature. Therefore, the energy from the sources is captured and channeled through the turbine devices and rotates the armature at high speeds inside the electric field produced by the magnets. Due to Faraday's law of induction, a middle of paper......many transmission, distribution, and generation devices and components. They will continually observe the operational capacity of the station paraphernalia in the substations, primarily as shown by the countless counters and gauges. They are also responsible for observing the switchboard's gadgets for strange operating conditions and mandate modification to restore the device to its normal operating capacity or remove it from service if necessary.
