Generator:
Generator is a electrical machine which converts mechanical energy into electrical energy.
(Define the underground cable.Explain the construction of underground cable and it's properties.) Underground cables: The transmission and distribution of an electrical power can be done with the help of overhead transmission line or by underground cables. In dense populated area like cities, the use of overhead transmission line is not practicable and in such a case we can use underground power cables. The underground cables of course come with other amenities, the advantage include smaller voltage drops and lesser probability of fault occurrence. On the other hand their production and installation cost is higher and used where overhead lines aren't viable due to practical limitations or risk involved. A typical underground cable consists of a conductor's covered by a number of insulating and protecting layers necessary for its satisfactory operation. Construction of Underground Cables: Conductor : Usually one, three or more (depending upon the application) conductors ar...
Instrument Transformer (CT and PT) (What is instrument Transformer? Explain it. Or explain about current transformer and potential transformer. Or explain construction details and working of CTs & PTs ) Current, voltage, power and impedance are the fundamental parameters of a power system. Condition of power system whether it is healthy or not will be determined by variation of these parameters from the values of those at normal operating condition. So the detection of fault and hence clearance of fault can be achieved if we can monitor these quantity throughout the operation. Normally power system variables are of very large magnitude in the range of Kilo Volts and Kilo Amps. It is very much costly and even impossible to use that quantity directly for control and protection but what we can do is that to reduce in proportionate amount and use that reduced quantity in required purpose. Transformer of special design used for that purpose are called instrument transformer. They ...
