really take the time to understand their home's electrical system and how electricians ensure that it is safe. However, by understanding this process and how it applies to your home, you can avoid unsafe wiring and non-compliance situations that can expensive to fix and dangerous to your home. Understanding The National Electrical Code The federal government has created a guideline for electrical wiring safety that is known as the "National Electrical Code." It has been adopted by all 50…

Dear Treehouse Board of Directors and to whomever else it might concern. Before I begin, I would like to give the assembled group of individuals a great round of applause. I thank you for the dedication and effort each of you has personally put into this theater to insure it’s survival for a great number of years. As a former student performing member of Treehouse Theaters JTF performing team, I wish to bring to the attention of the board an issue that I have personally been concerned about…

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…

Nikola Tesla The inventor Nikola Tesla lived from July 10, 1856 to January 7, 1943, he was a well-known engineer who designed the alternating-current (AC) electric system. He was born in what is now Croatia; he came to the United States in 1884 and worked for Thomas Edison for a while before they both went their separate ways. Tesla sold several patent rights to George Westinghouse; one of those was his AC machinery. During Tesla’s career he discovered, designed and developed ideas for a number…
