efficiency of electric current, discovered transmitting and receiving radio signals, created first RC boat, and his most popular invention the Tesla coil. Arriving in the US in 1884 at age 28, Nikola had always has the passion to advance the electrical engineering. His most famous invention, the Tesla Coil generates high voltage and a large magnetic field. The coil works at such a high voltage that it ionizes and gives the air an electric charge. This invention showed the…

one of Thomas Edison’s most famous engineering innovations. However the “Wizard of Menlo Park” (a name which he was also known as) has created and/or designed so many more inventions than just the light bulb. He has about 2332 patents worldwide proving he was really a great inventor. However, what proved his amazing skilling creating/designing are the useful products that are used throughout society till date. Edison’s inventions/designs such as the first electrical power grid, the light bulb,…

Chapter: 1 INTRODUCTION Basic theory of power transfer network We know that AC lines are operated at voltage level between 10kv to 800kv. The distribution network operates voltage level below the 100kv. For protection against fault circuit breakers are used. Power flow is obtained by receiving end power or sending end power. Ex. Consider a transmission line connected between load centre and generating station. We assume line is loss less and ignore line charging, then the power flow (P)…

Chapter 3 Interleaved Buck Converter System 3.1 INTRODUCTION Interleaved Buck Converter has lots of concentration due to its simple and low control complexity in application. where no isolation and high output current with low ripple. An No isolation DC/DC converter Fig.1.1 shows the step-down DC/DC converter. When switch M is on for the duration of dTs, power is transferred from source to load and filter inductor L is charged. When switch M is off for a duration (1-d)Ts, the diode D…

Rotor and touchdown bearing models Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor. Fig. 1. Rotor under investigation. In this work, the finite element model of the rotor employs…

When it comes to electrical issues, you never want to wait to get them fixed. Even if an electrical issue seems harmless on the surface, by letting the issue go unfixed you are actually putting you and your family at risk (and possibly other people if the issue results in an electrical fire that spreads). But, what exactly constitutes an electrical emergency? Realistically, you should always get an electrical issue looked at ASAP no matter how small, but there are certain electrical issues that,…

Modern power systems are made up of several interacting national systems. These systems interact providing essential support and monitoring in various power grids or sectors. While the advantages of systems interacting are bountiful in information gathering and sharing, it is not without certain drawbacks. Our society is dependent upon the availability of power and is quickly incapacitated by its loss. Simply observe the moderate disruption that is caused during severe weather. Often, these…

Ever since I was a kid I knew that I wanted to work with computer technology, and realized at an early age that I had knack for it, almost losing my technical certifications was an important literacy event in my life because it motivated me to pursue more education and ignited my passion of becoming an IT professional and working with computer technology. It all started when I decided to go back to school to get my A plus certification. I went to a technical school that focused on helping…

To start off building my computer, the case I decided on was the Thermaltake Overseer RX-I VN700M1W2N. I picked this case because I like being able to see the inside of the computer case, while offering a neat light display when powered on and a stylish look overall. The motherboard I have chosen is the ASUS Z170-A LGA 1151 Intel Z170 ATX motherboard. I have chosen this motherboard because I wanted something that is up-to-date, can run the everyday things I do, comes with USB 3.1, and is also…

inventions. After working together over a period of time Thomas Edison and Tesla decided to go their separate ways. Mostly because they had different views on the way the saw science. Tesla went through a couple hardships, he received money to start a company to develop the improvement of arc lighting then was…
