Laboratory Title Power Factor Improvement by Capacitive VAR Compensation   Objective The purpose of this experiment is to demonstrate the power factor correction procedure at a customer bus bar for three-phase loads.   Apparatus 1.         Lab volt Setup 2.         3 Phase Resistive Load 3.         3 Phase Inductive Load 4.         Power Supply Unit 5.         Connection Wires 6.         Data Acquisition and Control Interface 7.         Host Computer     Procedure         1.         At the beginning, all the equipment were connected according to the figure. The power supply was used to implement the AC power source. And, the resist...

  Introduction A belt drive is known as a looped flexible strip which is used to make easier the processes of machines and increase the efficiency of them. This mechanism includes pulleys on each shaft and one or more belts may be connected on each pulley to transmit rotary motion and power from one to others. Commonly belt drives are used for the purpose of transmitting power between a source and a load at a considerable distance. Belt drives are cost effective power transmitting method and free of lubricants. In real world, belt drives are widely can be seen in lathe machines, grinders, automotive systems such as fan belt, air conditioning compressor motor etc. Belts are classified in various types such as flat belts, V belts, and synchronous belts and round belts as for their different application purposes. Due to some beneficial facts such as easy installation, low maintenance, shock absorption, high efficiency, belt drives are widely used in industrial engineering applica...
