useful to reduce a network with several voltage sources and resistors to an equivalent circuit composed a single voltage source and a single resistance connected to a load only. It is used in simplifying and analysing complex linear networks power systems and circuits where one particular where a particular load resistor‚ RL in the circuit is subject to change‚ and recalculation of the circuit is necessary with each trial value of load resistance to determine voltage across it and current through it.

found in the literature. These problems have become one of the major concern‚ especially‚ with the use of power electronics devices which are sensitive to the variation of power supply. Among these problems Voltage Sag & Swell are identified as major concern to the electrical consumers. Voltage Sag is one of the most occurring power quality problems that cause severe problems and losses to industry. With the power systems restructuring and shifting trend towards distributed and dispersed generation

discuss different types of network theorem and their applicability in networks. At the end‚ we will consider the star and delta transformation. The objective of analyzing a particular circuit is to determine the various responses such as current‚ voltage etc. which are produced in the circuit by the presence of active elements. Objectives After studying this unit‚ you should be able to • give the elementary description of network terms and definitions‚ • explain the superposition theorem‚ reciprocating

Pilot trolley method for trains AIM: To design a auto pilot trolley method for trains. Base Technology: EMBEDDED Abstract: It is a very useful project. By using this we can reduce the more train accident. The trolley is communicating with the train using ISM based RF signal. 432.92 MHz frequency signal is used for communication. As we do the project we use this frequency. It will sense the object using the IR signal‚ bomb is detected using metal detector‚ track open is sensed using limit

chapter 1 intaoduction “Driving to save lives‚ time‚ and money in spite of the conditions around you and the actions of others.”- This is the slogan for Defensive Driving. Vehicle accidents are most common if the driving is inadequate. These happen on most factors if the driver is drowsy or if he is alcoholic. Driver drowsiness is recognized as an important factor in the vehicle accidents. It was demonstrated that driving performance deteriorates with increased drowsiness with resulting crashes
