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!

I am a graduate engineer in electrical engineering, I have more than 10 year of working experience in Power Generations of verious Ltd company in relocated all over India and with open to all rules and responsibilities.
Thankyou!, but i need autocad app
I have a question , all these spreadsheets will work well on a Mac ? Is there a fee or a price ?
Thanks
Hello.
How can I download Residential Load Calculator? Do I have to sign in?
Do these sheets work in Google Sheets? If yes, has anyone figured out a way to make the calculations work right? I’ve tried to open the .xlsx files in Google sheets but the formulas won’t work.
Most of these sheets have macros working behind and that’s why they don’t work. Maybe there’s some way to activate macros in G Sheets.
I was wondering if an installation of capacitors in some motors of a cargo ship is meaningfull and efficient.
I was thinking to add capacitors to 5 motors of 55kw each, which are operating 24/7/365 and reduce their reactive power.
Read so many articles, that i am now confused.
Of course it will be of a profit but at the same time i am very interested in the vessel’s power grid safety and stability too.
hello sir,
i want to learn how can i read a electrical drawing in simple way.
thank you
Hello sir,
I want voltage drop calculation formula for selection actual cable size.
Good day.
I hope you could assist me with some advice please, as getting any reaction from solar companies, seems impossible!
I reside in Augrabies and do irrigation from an irrigation canal on the lower side by means of flood irrigation. On the higher side I use electric water pumps. The bigger one for irrigation and the smaller one for drinking water to a tank.
I currently use power from Escom, but want to change it to solar power.
The big pump takes water directly from the canal and it is mainly used during daytime.
The small pump is on a borehole which is 14m deep and the watertable stands at 8m. It is usually used during daytime as well.
I would be so grateful if you could assist me with the correct different solar equipment needed, please. The battery, solar panels, inverter and controller.
Thank you so much.
Friendly regards.

I need a excel spreadsheet that calculate earthmoving machine’s working hrs per day worked exmple machine start hrs is 525 next day beginning hrs is 550. Hrs worked is 25 hrs and per month and also in the calculation it must redflag you on when its due for maintenance service. Maintenance services is normaly after 250hrs, 750hrs, 1000hrs or 2000 hrs. as soon as the machine reach his next due maintenance service hrs, the spreadsheet warn you by redflagging the hrs.
Feel free to contact me if you need any other information.
Hi Alet,
it would be interesting to work on it & prepare a master data sheet for you.
@Alet kindly drop an email with details on my email : [email protected]
thanks.
I need more app on Electrical design
Please how do I open an account to login to the site.
Great website with huge bunch of knowledge.
Hello sir
I want to simulate electric and magnetic field under power line
Could I have thé EF and MF CALC software?
Thanks
