## 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 more easier, alowing 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 expirienced electrical engineers and programmers (thank you mr. Jignesh Parmar!) and by well known manufacturers of electrical equipment. They all really did an awesome job, you must admit!

Just to mention that all calculation spreadsheets are **free** for download! ;)

on the spreadsheet for the calculation of “Load Listing, Calculations & Generator Sizing” why is the default voltage 400 volts rather than the residential voltage of 240 volts? It would be a more useful spreadsheet if you can actually size the loads for a residential home. Thanks, John

Dear Sir,

we need a Dc cable Calculator for find out the size of cable for varies DC motor or invertor.

dear your are doing good job for preparing such excel sheet.

I am requested to prepare excel sheet for calculating per unit value for common base particularly 100 MVA base for transformer, transmission line for all conductors. generators

Thank You very much. Your article is of great help to me as an electrical engineer. It will surely boost my electrical strength.

can you plz upload a sheet that contains calculation of energy savings by correcting the harmonics in the system

Thank you for sharing these tools for calculations, they are very helpful.

Thank You EEP

Its very useful

its very good

where is download link

thanks

Thankyou very much, so great.

Very useful. Thank you very much EEP. :) More powers!

Good program

Thank you for all these incredible calculation sheets. Really welcome!

Great job. Thank you a lot for sharing.

These sheets are fabulous. An ample list of topics for calculations have been covered. It shall of great use to electrical engineer.

Thanks a lot for sharing these resources and that to free of cost.

Appreciate efforts of all involved !!!
