This comprehensive section is prepared as a resource for individuals and professionals interested in the electrical engineering career path.
Power Substation Handbooks Substation engineers nowdays are involved in projects from design and conceptualization to maintenance. Because of the wide range of industries using electrical engineers, many engineers specialize in some of the sub-discipline of electrical engineering.
Depending on background and expertise, projects can include systems such as energy transmission and distribution, protection and control etc. These spreadsheets developed by enthusiasts will make your job much more easier, alowing you to shorten the time used for endless calculations of power cables, voltage drop, power factor, circuit breakers, capacitors, cable size, power transformers etc.
Just to mention that all calculation spreadsheets are FREE for download!“Learning a new language gives you a window into someone else’s world,” says Virginia Adams, who graduated from MIT this past May. For Adams, learning Chinese has given her a glimpse into a fascinating, fast-paced culture where technology is rapidly advancing.

This course relies on primary readings from the database community to introduce graduate students to the foundations of database systems, focusing on basics such as the relational algebra and data model, schema normalization, query optimization, and transactions.
It is designed for students who have taken (or equivalent); no prior database experience is assumed, though students who have. Whether you are a high school student looking forward to graduating and moving on to a career in electrical engineering or someone looking to go back and study a different field than the one in which you currently work, it can be difficult to find programs and courses suited to .
