Please give your suggestions to help make the site better. This is a complete reference of electrical engineering and technology.This site covers many important topics related to different parts of power system engineering, like, basic electrical, electrical power transformer, electrical switch-gear, power system protection, electrical power transmission system etc. The site provides many video presentations for different electrical theories to make your electrical engineering study more easy and understandable. In few words, it can be said that this site covers almost all topics related to electrical power system engineering and technology.Electrical EngineeringThe most familiar form of energy in our daily lives is electrical energy. The branch of engineering which deals with producing, managing and utilizing this energy, is referred as electrical engineering. This field of engineering was introduced in an organized manner in the mid of 19th century. Electrical technology is not as old as civil and mechanical technologies. Interest in this field of study grew after the invention of electricity. It was June 1752 when Benjamin Franklin first tried to catch electricity from clouds during a heavy storm with the help of a flying kite. This was the beginning and to date still we are trying to manage this energy. Managing electrical energy (producing, transmitting, distributing, utilizing) is nothing but electrical engineering. Commercially this became an occupation only after 1950.
