Available fault current spreadsheet

Available fault current spreadsheet


This MS Excel Spreadsheet is created by mr. John Sokolik and it represents 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.

    this is a very good website!

  2. .
    I work with Electricity Authority of Cyprus and i am the section head of High voltage cables.
    I really enjoy reading your articles. They are very good and very helpful.
    I am using your spread sheets for various calculations.
    Thank you

  3. […] and the EGC, the grounding clamp mechanically anchors the EGC to the cable tray so that under fault current conditions the magnetic forces do not throw the EGC out of the cable […]
