The Pinceti model [8] was derived from the IEEE WG.3.4.11 [5] recommended model with some minor differences.
The IEEE WG. 3.4.11 and Pinceti models areshown in fig.
1 and fig. 2 respectively.
The parameters defined by Pinceti model can be adopted using the two given rules
1.
The non-linear resistors characteristics (A0 and A1)are based on the curves shown in fig. 3. These curvesare derived from the curve proposed by IEEEW.G.3.4.11, and are referred to the peak value of theresidual voltage measured during a discharge testwith a 10kA lightning current impulse
