Three-phase electric power

Before we know about power quality audit we must know about what is audit. Audit The word audit is derived from a Latin word "audire" which means "to hear". During the medieval times when manual book-keeping was prevalent, auditors in Britain used to hear the accounts read out for them and checked that the organisation's personnel were not negligent or fraudulent. Quality Audit Quality audits are performed to verify conformance to standards through review of objective evidence. A system of…

Croatia. His father was an Orthodox priest. His mother, had a knack for home craft tools and machinery. Tesla was the fourth of five children. He was such a genius that he could do integral calculus in his head and graduated with a four-year term in three years, graduating in 1873. In 1882, he got a job at the Continental Edison Company. Because of his advanced skill in engineering and physics, he was soon designing improved motors. Tesla worked every day from 9:00 a.m. until 6:00 p.m. or…

Vehicle-to-grid (V2G) is one power technology of those attractive new energy storage technologies. It aggregated those vehicles with battery (Hybrid electric vehicles, battery electric vehicles, and plug- in hybrid electric vehicles) into the grid as a distributed resource of energy load, storage and generation device. It is not only adding the ability to deliver power from vehicle to the grid, but also can apply the power flow (Lund & Kempton, 2008). V2G technology provides potential solutions…

Abstract:It is very important to control the speed of induction motors in industrial and engineering applications. Efficient control strategies are used for reducing operation cost too.This paper presents a direct flux and torque control of three phase induction motor drive using PI and Fuzzy logic controller. The Direct Flux and Torque Control (DTC) is one of the most excellent direct control strategies of stator flux and torque ripple of Induction Motor Drive(IMD). The conventional method of…

Moderate initial cost followed by a higher operating cost and maintenance. High purchasing price; Lower operating cost and good energy saving which cut down operating cost. Table 2 summary of comparison between PM and induction machines losses in electric machines To investigate the efficiency of the machine, an essential part is to evaluate the losses in the motor. Losses in the machine is determined by the structure and working condition. Losses in the machines can generally be divided…

His next goal was to transport power wirelessly, and also send and receive signals across the world. Tesla purchased 200 acres from James Warden in 1901, in order to create a wireless telegraphy plant. Tesla then had a 187 foot tall tower built, with a 120 foot foundation in the ground…

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…

Tesla was born in Croatia on July 9th, 1856. “Throughout his lifetime, he pursued seemingly impossible dreams including wireless transmission of power (the phenomenon of transferring energy without wires through the use of electromagnetic induction is still known as the Tesla effect).” The use of the tesla effect is commonly used in electric toothbrushes so that they can stay completely watertight, it is also in the wireless phone chargers. “He also devised a system which anticipated World-wide…

Case Study: Germany to Give €1Bn Subsidy to Boost Electric Car Sales Name Institution Case Study: “Germany to Give €1Bn Subsidy to Boost Electric Car Sales” Seen as a dedication to meet the national climate goals with zero-emission mobility, Germany will subside all electric car purchase to boost the slow growth of the sector. For instance, the buyer will receive a subsidy amounting to €4,000 for the purchase a purely electric vehicle and €3,000 for a hybrid. With the…

Everyday our brains are inundated with seemingly mundane details, and remembering all of them is impossible. Unfortunately in some cases, previously acquired memories can become important later, even if they did not seem important at the time. For instance, in situations where they have an effect on the future health or safety of the individual. In this study, Dunsmoor et al. (2012) ask the question: can seemingly unimportant information be strengthened and remembered later if connected to an…
