1. Introduction to Power Engineering 1.1 Power System Functions The traditional power system is arranged as a hierarchy. Generators feed into a high voltage transmission system that facilitates bulk transfers of power over large distances. Connected to the transmission system are medium voltage distribution networks that take power from grid supply points and deliver it to the customers who are supplied a low voltage. For a lot of its history‚ the electricity supply industry has operated as

Amid my undergrad program I took in the different basics of Electrical and Electronics Engineering which together with common sense coursework fortify hobby. Right from my school‚ I had a keen interest towards Mathematics‚ Science and research in general. This essential interest drove me to take up Mathematics‚ Physics and Chemistry as my significant

I chose to study Mechanical Engineering because; they say it is the mother of all engineering. Be it Electrical engineering‚ chemical engineering‚ civil engineering without mechanical engineering all of this branches of engineering are useless. Our daily live is almost impossible to live without components that are made up of mechanical part. The pencil we use is been operated by the help of a simple mechanical design. All of these simple mechanical ideas have either made people rich‚ countries have

I think biomedical engineering is morally correct. Biomedical engineering has saved many many lives and allows people to live a normal life just like everyone else. If you aren’t sure what biomedical engineering is‚ it’s when you take a malfunctioning‚ or not working organ‚ and replace is with another working organ. It could be a real human organ‚ or a man made organ made of plastic and metal. For example‚ it could make someone who doesn’t have legs or arms‚ have and use arms as if they never didn’t

industrial and system engineering in the management of the semiconductor industry especially in dealing with optimizing complex processes and systems. My team and I are constantly looking for new ways to improve our processes such as optimizing tool processing time to increase productivity. More than often‚ we are involved in data analysing and looking for new ways to solve problems effectively. I realised that my passion and job satisfaction comes from being able to find engineering solutions to chronic

THE BENEFITS THAT ENGINEERING HAS BROUGHT TO THE WORLD INTRODUCTION Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between scientific discoveries and the commercial applications that meet societal and consumer needs. They also use their imagination and analytical skills to invent‚ design‚ and build things that matter. They are team players with independent minds who turn ideas into reality. Many become
