  • Publication number: 20160091553
    Abstract: An arc flash hazard assessment method includes storing electrical equipment data in memory, defining an arc flash model function based on the data, and estimating the model function based on a weighted average of interpolated and extrapolated values. The electrical equipment data may include an operating voltage, a fault current, and a clearing time. The model function is defined for at least three reference voltages V1, V2 and V3, with the interpolated value at operating voltage V, between voltages V1 and V2, and the extrapolated value from reference voltages V2 and V3. At the arc flash protection boundary, the estimated model function has a predefined incident energy value of 1.2 cal/cm2 (or about 5.02 J/cm2), or less.
