Farhana Umer Lecturer DEPARTMENT OF ELECTRICAL ENGINEERING University College of Engineering and Technology, The Islamia University of Bahawalpur YEAR-2012 Table of Contents Abstract †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦..vii Acknowledgement ix List†¦show more content†¦Power System fault is defined as undesirable condition that occurs in the power system. These undesirable conditions such as short circuit, current leakage, ground short, over current and overvoltage and over-temperature. With the increasing loads, voltages and short-circuit duty in distribution system, over current protection has become more important today. The ability of protection system is demanded not only for economic reason but also consumers just expect ‘reliable’ service. In a Power System Protection, the system engineer would need a device that can monitor current, voltage, frequency, temperature and in some case over power in the system. Thus a device called Protective Relay is created to serve the purpose. The protective relay is most often relay coupled with Circuit Breaker such that it can isolate the abnormal condition in the system.

There is a reference point for temperature. When temperature of air goes higher than that circuit will take a decision of turning on the fan or motor automatically. Circuit of our project is a small closed loop control system. In this circuit there is comparator as decision maker, Thermistor as temperature sensor, DC AmplifierRead MoreEnvironmental Management Structure And Responsibilty2716 Words   |  11 Pages†¢ 1.4 Environmental Policy 2.
