Frank Sprague’s electric trolley system became the first large-scale electric rail system in the world; in 1911, General Electric unveiled the first electric refrigerator. However, the rise of electricity was fraught with conflict over the type of electrical current. Starting in the 1870’s the fight over electric currents,…

Discipline Investigation: Network System Analyst Introduction Information system is the most popular technology in the past two decades, but I have decided to get into the field is not because of the popularity. I have chosen network analyst as my future path because my mom used to restrict my internet usage. The reason sounds unique but that is why I initiate my interest on this “forbidden thing”. However, I never learn anything about it until I took a class in my high school, call Network…

ACKNOWLEDGEMENT It is my pleasure to thank all those who helped me and made my project work a success. I would like to thank my parents who made this research possible and for extending their moral support and patience. I like to thank the Principal of our Institution, Prof. Parvardhavardhani Gopalakrishnan as well as the Project coordinator, Prof. Y.G. Tharakan, for all the patience and guidance provided to me throughout the dissertation period. I take this opportunity in expressing the…

Harmonics: Harmonic distortions are injected at the generation as well as the consumer end. At the consumer end, harmonics are caused by nonlinear loads such as PCs, CFLs, electronic devices, etc. The harmonics distortion caused by non-linear load such as electric arc furnaces, large concentrations of arc discharge lamps, variable speed motors, saturation of magnetization of transformer and a distorted line current. The current generated by such loads will interact with power system impedance…

SIMULATION RESULTS AND DISCUSSION 4.5.1 Compensation of Voltage Sags All the proposed controllers performed to the IEEE standard. Table 4.5 shows voltage sag compensation of the proposed intelligent controllers. Compensated SS value shows the voltage sag compensation capability of the each proposed controller under different fault types and load conditions. In case 1, performance of DVR with proposed fuzzy logic controller has the sag score 0.5056pu observed at sensitive load before…

George Westinghouse. Here, he established a laboratory, Tesla Electric Light, where he improved on his alternating current motor. He also began to work on inventions that were not possible without the motor, such as the Tesla coil, a high voltage electrical transformer, which is still used in radio technology today. In building it, Tesla wanted to bring power to the world, wirelessly. Tesla also experimented with X-rays and demonstrated radio communications two years before Marconi. In fact,…

BUSINESS LAW ASSIGNMENT ACKNOWLEGMENT I am using this opportunity to express my gratitude to everyone who supported me throughout the course of this project. I am thankful for their aspiring guidance and friendly advice during the project work. This project has helped me expose myself to new information and learn a lot from it. I express my warm thanks to Ms. Geetanjali Chandra for providing me with this challenging project and her support and guidance. Thank you…

Electrical Properties AC Conductivity, Ac Resistivity, Dielectric loss, and Dielectric constant are electrical properties and measured as a function of frequency. AC Conductivity and Resistivity AC resistance (ρac) was recorded by LCR meter model 4275 in the frequency range 1MHz to 3GHz. AC conductivity was determined by using the value of Ac resistance. As we know, Ac Conductivity is reciprocal of Ac resistance can be calculated by the relation; ac =1/ρac (6) The variation of AC…

Fig. 3. Schematic Diagram of Power Line Guardians (“PLG”) PLGs are also used to give the real-time data on the lines such as: line current, conductor temperature, frequency, sag [17]-[21]. Fig. 4. The PLG communications system. The diagram (Fig.4) shows the PLG communications system. PLGs (blue) control the power flows on the lines. Super PLGs (red) can control both the power flows and the PLGs. These Super PLGs are also used to communicate with Energy Management Systems (EMS) and allow…

task 2.4 how a laboratory 's design can affect its functionality in this report i will be going over the qualities that are affected by a laboratory design efficiency: efficiency can definitely be affected, if you were to place the sink away from the food preparation area in a food science lab then meat, fish and other food items could not be washed or prepared as efficiently. so in order for the efficiency to be maximised there should be several features in a lab that are kept close together…
