1. INTRODUCTION 1.1) INTRODUCTION OF 3 PHASE INDUCTION MOTOR: The three phase induction motors are used in many industrial applications due to their reliability‚ low cost and high performance. Whereas this popular ac motor performance is affected by following type of faults. 1. ELECTRICALLY RELATED FAULTS (33%): The faults under this classification are single phasing‚ over/under voltage‚ overload over temperature. 2. MECHANICAL RELATED FAULTS (32%): The rotor winding failure‚ stator winding failure

2. Dual-loop Control of a Grid-Connected Inverter In this section‚ the modeling and control of a grid-connected inverter with dual-loop control using the capacitor current feedback is described. Although‚ this issue has already been addressed in available literatures‚ the goal is introducing a simplified block diagram which make designing controllers easier. A grid-connected inverter with the LCL filter is shown in Fig. 1. The LCL filter consists of an inverter-side inductor L1‚ a filter capacitor

Power Distribution Reforms in India – A journey from Monopoly towards Competition. Case Objective: Power a basic human need is the critical infrastructure on which modern economic activity is fully dependent. Only 55% households in India have access to Electricity. Most of those who have access do not get uninterrupted reliable supply. In this era of globalization‚ it is essential that electricity of good qualities is provided at reasonable rates for economic activity so that competitiveness increases

Power System Fault Analysis 2.0 Introduction The fault analysis of a power system is required in order to provide information for the selection of switchgear‚ setting of relays and stability of system operation. A power system is not static but changes during operation (switching on or off of generators and transmission lines) and during planning (addition of generators and transmission lines). Thus fault studies need to be routinely performed by utility engineers (such as in the TNB). Faults

Julie Ouk Mr. Salisbury British Literature 24 September 2012 Prime vs Tron From my perspective‚ Optimus Prime best resembles Beowulf’s character. Beowulf was a strong leader of all the Geats and strove to prevail against all evil. He sacrificed his life on several occasions to protect his people and prevail against any villainous creature. Like Beowulf‚ Optimus Prime is the leader of all Autobots. He has a strong leadership against his race for he has always shown strength even at his weakest

Measuring the Resistivity of Copper Wire of Different Lengths In this report I will be writing about the experiment I will conduct on copper wire of different lengths. The dependent variable I will be measuring is the resistance of the Copper wire. To do this experiment‚ one needs to obtain measurements with a high degree of accuracy‚ taking care of the equipment they use and measuring each value to a certain degree of accuracy for all results. The problem with measuring the resistivity of Copper

Electrical Power System By Cameron Cooper The electrical system on the C-12 is a 28 volt system. It also has single phase‚ 400 hertz‚ 115 volt and 26 volt AC power systems. The AC power is provided by two inverters. The main 28 volt electrical power for the C-12 is supplied from any combination of: -One 28 volt‚ 42 amp hour lead acid battery or One 28 volt‚ 34 amp hour nickel cadmium battery (depending on the model); -Two parallel 28 volt‚ 250 amp starter generators on each engine; -One
