First AFB interpolation term

Second AFB interpolation term

Third AFB interpolation term

When 600 < Voc ≤ 2.7 the final values of incident energy and arc-flash boundary are given as follows:
AFB = AFB3

When Voc > 2.7, the final values of incident energy and arc-flash boundary are given as follows:

AFB = AFB2

Where:

AFB1 = First AFB interpolation term between 600 V and 2700 V (mm)
AFB2 = Second AFB interpolation term used when Voc is greater than 2700 V (mm)
AFB3 = Third AFB interpolation term used when Voc is less than 2700 V (mm)
AFB600 = Arc-flash boundary at Voc = 600 V (mm)
AFB2700 = Arc-flash boundary at Voc = 2700 V (mm)
AFB14300 = Arc-flash boundary at Voc = 14,300 V (mm)
VOC = System open-circuit voltage (kV)
