Electrical tools (MS Excel Spreadsheets)
This section is dedicated to tools every electrical engineer can use in daily work. These spreadsheets below will make your job much easier, allowing you to shorten the time used for endless calculations of cables, voltage drop, various selections of circuit breakers, capacitors, cable size, and so on.
Spreadsheets are mostly developed by experienced electrical engineers and programmers and by well-known manufacturers of electrical equipment. They all really did an awesome job, we must admit!

Good to expand knowledge in respective field.
Really EEP is a great Electrical portal, thanks all associates with it for it’s enrichment, updating, upgrading and implicit contribution to the society of electrical professionals.
Awaiting eagerly to submit some articles for publication on EEP very near future!!!!!!
A great professional platform that allows us to solve problems .
Thank you ver much.
I am a new member of the Premium Pro and I’m pretty sure that I’ll learn a lot and enjoy it at the same time
Thanks a lot
I am interested in the EEP.
I have read several good articles.
I am planning to enter into a membership plan but the question that I have is are the courses that are offed and completed successfully qualified for PDH credits for the state requirements for annual PE continuing education courses.
Thank you for offering such courses.
Andrew Herbert, P.E.
It is too much supporting to expand know-how of knowledge of the respective field.
Good to expand knowledge in respective field.
Kindly, do you have an excel spreadsheet regarding siemens distance protection relays(siprotec4) used to calculate protective zones impedances?. If the answer yes can you post it in this your website.
I hope to receive your reply very soon
thank you so much
Thank you so much for sharing all these tools and documents. These are very important for our business
Do yo have power system security, Load Flow Analysis and contingency analysis excel sheet?
Thank you very much
Hi , Do you have SOLAR Farm design calculations for selection of fuse, 1500V DC wire harness selection, tracking calculations etc.
spreadsheet for star delta starters calculations is protected. how to use it
I like this Portal since long time ago…..
Thanks for the good Job
i need refererence to start learning electrical systems from scratch, which is the best books to start with
