Alternating current

over his work allowed him to make numerous contributions to the world of electricity, many of which helped to usher in the high tech era which we are accustomed to today. Most people are aware of at least one of his discoveries, whether it is alternating current, wireless communication, or wireless controlling, but few people are aware that Tesla may have made another discovery which was more fantastic than all of the others combined. Tesla may have picked up a signal from another world. And…

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…

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…

All of these men were American scientist and businessman who helped Tesla advance his research or career. Thomas Edison allowed Tesla to showcase his talent even though he eventually gave him nothing for his work. “Tesla promptly quit and took a job digging ditches. But it wasn’t long before word got out the Tesla’s AC motor was worth investing in, and teh Western Union Company put Tesla to work in a lab..” (King, pg. 2). Tesla’s time with Thomas allowed him to get exposure and move on to…

These two field magnets always have opposite polarity. On the middle of the motor there is an armature, two commutators and two brushes. When current flow though the two brushes, one of the brushes touches commutator plate 1 and the other brushes touches commutator plate 2. Then the armature A and armature B turn in to field magnets, because when the current flow though iron that coil with wire, it will produce a strong electromagnetic field. This means that armature A and armature B must have…

Nikola Tesla was, in my opinion, a great inventor that could have changed the entire world. Tesla was born in a small village called Smiljan in Austria. After his genious 12-year old brother passed away, Nikola, who was 5 years old, was pressured into studying. He studied chemistry, engineering and philosophy. He later emigrated to the United States of America in 1884, where he was offered a job at the company of Thomas Edison. He quit his job a few months later after a disagreement over his…

6/10/2015 Mrs Rummins | GRUJICIC, Marko Background: Another name for I/V characteristics is current-voltage. Current and voltage are the factors that are being investigated, there characteristics and effects in diodes of different colours. The Current or I in I/V characteristics refers to the flow of an electric charge. It is often carried out by electrons when moving through wires Materials: -green, red, blue, yellow coloured diodes -breadboard -wires - 2X multimeters, 1 as a voltmeter…

Mechanical power is defined as torque and RPM (rotation per minute) and electric power is defined as current and voltage. Therefore, in order convert mechanical power into electric power, torque shall be converted into current and rpm shall be changed into voltage. The relation between the rpm and voltage can be defined with equations with the use of Equations. When there is a decrease in value in equations there is an increase in efficiency of power generator. In here, there is no loss when…

Who was a better inventor LeoNardo DA Vinci or Thomas Edison? It has been long debated on who was a better inventor, Leonardo DA Vinci or Thomas Edison? Thomas Edison might have been a leading inventor in his time, because he created the light bulb but that was really his main achievement. Leonardo DA Vinci was better because he had more inventions, better known for his work, and he was specialized in many lines of inventing. Now you really need to think Thomas Edison was responsible for…
