The software was created by Alan Privette of Duke Power, a utility company in the United States. It is offered with no claims from Duke Power or any other company to guarantee its accuracy or reliability. It is intended to be used as a guide only and not as a substitute for a thorough hazard assessment by a qualified electrical safety professional.
The software requires you to enter five parameters: the arc current in amps, the arc gap in inches, the supply voltage in volts, the distance from the arc to the receiving surface in inches, and the duration of the arc in cycles. The software will then calculate the total calories per square centimeter (cal/cm2) at the receiving surface, which is a measure of the incident energy of the arc flash.
The software assumes a single-phase arc in an open configuration. If your work involves a multi-phase arc or a confined space, you will need to apply a suitable correction factor to the results of the calculator to better approximate your actual conditions. You can find more information about these correction factors in the documentation of the software.
The software has a simple user interface and runs on DOS. It does not include error checking, so you need to make sure you enter valid numbers. If you make a mistake, you will need to exit from the software and start over. You can also exit from the software by holding down the CTRL key and pushing the BREAK key on your keyboard.
