Calculate fault current
This MS Excel Spreadsheet represents an easy way to calculate fault current by entering few values in indicated fields. You will find sheet with very nice example already fulfilled. Before starting fault current calculation, you will have to choose between Step 1a and Step 1b which are explained below.
Step 1a
Insert available fault current ampere rating from your local Utility.
Step 1b
Insert the the kVA rating power factor (PF) and impedance (Z) of the transformer is not required to continue. Note: When you insert the kVA rating power factor and impedance you must select the voltage from the dropdown box Select Voltage & Phase before the value will be calculated.

Is there a way to unlock the spreadsheet so I can run calculations on 277/480V?
Just use one of the on line password breakers – Google is your friend !
I would like to download various MS Excel Spreadsheets offered on the website. Do I have to be a member? If so, what type?
…..thanks
i use 11/04kv transformer but this sheet no option of this voltage level
Can someone please explain the source of the conductor constant C? What does that signify? What is the unit? What is the equation?
I know this has something to do with resistance/distance but can’t really relate how
very good tool for projects.
Hi,
Very good work.
Yet could you make an option which allows you to input the cable data in mmsq and not in AWG (European Standards)?
Thanks in advance.
Thanks a lot, it’s a big help. you’re so kind.
Nice Information . Thanks
The tools are most valuable materials that will empowered young and existing engineers to grow in their field of operations.
Much useful, thanks.
I am an electrical engineer at the Federal College of Education Yola
I work in the Electrical section of Works Department
I really really enjoy your articles keep it up please.
Thank you, sir
good article
