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!

Sure they are still downloadable…
Could you please make it easier to unsubscribe. I no longer want all those notifications because there are way too many.
very useful
so great tools i found here my pleasure to reach your portal many many thanks for such time saving tools
if possible looking forward to hyadaulic pump motor sizing spread sheet
thanks
Can you help me download this spreadsheets?
I think its so easy just click the link with “RIGHT HERE” next to the download
Yes it is for grid modernization of Ethiopian electric power program
I want download thé excel data
Is there a possible way to get standard technical specification for preparation of international bid for laboratory equipment of electric power company
Hi, a good day to you at EPP.
I am an entrepreneur looking into setting up a cassava starch manufacturing factory. The power requirement of the processing line is about 180 – 200kwh.
Firstly, I will like to ask – is your organization based in Nigeria?
Secondly, I want to ask that for this kind of project, how much will it cost If your team or organization were to install this project? Let us assume the plant site is 15km away from a 33KVA power source.
Have not visited the site for a long time. The Excel calculation Spreadsheets can not be downloaded anymore.
Hello,i am Ismaila from Nigeria,i have installed a 1mva transformer and a 500kv one,i keep having an over voltage reading of above 250v when read on face to neutral and over 450v face to face reading.i am sure that my neutral grounding is adequate and efficient.i have also factored my incoming voltage and arrived at most appropriate TAP,i have also altered all TAPS and all produces till yet high voltages.pls advice on any other options i may have..Thank u 4 your anticipated support.
What is the % of load you are ruining the Tr-r. at?
