Electrical conductor

I graduated from the University of Houston, Texas with a Master of Science degree in Electrical Engineering with Thesis in May 2011. My engineering work experience as an Engineer-In-Training began at En-Fab, Inc. in Houston, Texas from June 2011 and since then I am working as an Electrical Engineer in this company. My engineering experience at En-Fab, Inc. entailed being a member of the project engineering group where I performed calculations for sizing of the motor and branch circuit overload…

Safety in the Electrical Field In today’s world, every job pursued comes with a certain level of risk. Whether it be a financial risk or risk of a physical injury, one must be prepared to face anything. Electricians are at an extremely high risk of causing physical harm to themselves while on the job. As the number of electricians who enter the work force continues to rise each year, the risk of on-the-job injuries doubles. Some of the most common, yet dangerous risks electricians face every day…

hence equation 3.9 reduces to 3.8. Furthermore, when the conductivity increases, the dielectric time constant decrease, thus the field distribution can reach the steady state condition rapidly. The three equations 3.2, 3.3 and 3.4 demonstrate the electrical behaviour of a weakly conductive of insulation material, while equation 3.9 which is the result of combining these three equations describe the accumulated space charge when the time derivation of current density is not zero and the ratio…

companies often generates decisions that often have questionable ethics. Whether to sacrifice safety conductor on site just to save a few dollars or providing deceptive advice to obtain the upper hand, unethical forms of conduct is weakening the industry of construction, thus codes of ethics were developed widely across multiple businesses. As I investigated the case study involving an electrical engineer, who worked for Dicers, there were multiple instances where the company has failed to…

Thomas Alva Edison possessed a tremendous amount of skills as an inventor and dedicated a great amount of time and efforts in his laboratory. Edison realized at a young age that creating and inventing intrigued him. He drafted a great amount of notebooks containing sketches, ideas, and explanations for his inventions. His ambitions and aspirations led Edison to own many companies and accumulate over 1,000 patents for his inventions. As an inventor, Thomas grew up with a mindset that he would…

(similar to electric battery) to produce a steady flow of electric current by using the chemical reactions. His great invention is that “he transmitted the electricity by linking positive and negatively charged connectors and driving voltage or electrical charge through them. In 1831, Michael Faraday made a crude power generator (known as electric dynamo) to solve the problem of generating electric current in practical way. So it became feasible to use. He used the magnet in his invention. In…

parallel, and series-parallel. In a DC series circuit the components are all wired together from end to end with the same amount of current flowing through each component. In a simple series circuit all that is required is a power source (battery), conductor, and a resistor. In order to better understand how a series circuit works you must first begin to understand how each of the basic components function and contribute to…

covered. The differences between PM machine and conventional AC machines Induction machine is also called “asynchronies machine”. The rotor is placed in a rotating magnetic field and thus a rotating force can be attained. The rotor is a rotating conductor and is mainly produced in cage shape. The stator generates the rotating magnetic field. The rotating of the magnetic field is not achieved by mechanical principle rather by applying AC current to the stator. The AC current applied to 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…

John Mauchly pioneered the field of computer science and built the foundation for all modern computing with the creation of the world 's first fully functional digital computer, the ENIAC. The ENIAC, completed in 1946 at the University of Pennsylvania, occupied 1800 square feet, weighed 30 tons, had 18000 vacuum tubes, and cost about $5,000,000 in modern dollars (ENIAC Definition from PC Magazine Encyclopedia). John Mauchly originally conceived the ENIAC as a tool for statistical weather…
