## Calculate fault current

This MS Excel Spreadsheet is created by mr. John Sokolik and it 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 Â (Z) of the transformer is not required to continue. Note: When you insert the kVA rating Â power factor and impedance you must select the voltage from the dropdown box Select Voltage & Phase before the value will be calculated.

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

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)?
