From the day of invention of Electricity, the distribution of Electric Power from the generation section to the end users through different stations are being world widely carried out. Different types of components are being used at different stages for the purpose of Generation, transmission, distribution and protection. In the conventional mode of Power system analysis, the calculations & the system analysis and modelling were done manually in which the overall efficiency was not achieved properly. ETAP is Electrical Power System Analysis & operation software which offers a power system modelling, analysis, simulation, monitoring, control and optimization can be carried continuously till the operation in all stages of a Power system life cycle. Electrical engineering jobs involve designing, developing, testing, and supervising the manufacturing of electrical equipment, systems and components. So, in today’s scenario with the knowledge in this widely used tool an Electrical Engineer can easily grab a spot for him in this automotive world.
