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 V, Vand V, with the interpolated value at operating voltage V, between voltages Vand V, and the extrapolated value from reference voltages Vand V. At the arc flash protection boundary, the estimated model function has a predefined incident energy value of 1.2 cal/cm(or about 5.02 J/cm), or less.
