The normalized incident energy is used to calculate the incident energy at a normal surface at a specific distance and arcing time using the formula (4). ' L4.184 Ù ' á @ ç. A @ 5 4 ½ A ë (4) where E= incident energy (J/cm2) Cf= Calculation factor =1.0; voltage >1kV =1.5; voltage <1kV t= arcing time (seconds) D= working distance from arc. The level of the short circuit current will depend on: the transformer secondary voltage rating and impedance; the impedance of the generators; the impedance of the circuit from the transformer to the short. To simplify the fault current calculation it is assumed that all electrical generators in the system are in phase, and that they are.
