$SIL = ( V_(LL) ^2)/ Z_0$

(V_{L L}) line-to-line voltage

The Math / Science

The Surge Impedance Loading is the characteristic impedance of a transmission line in electric power transmission. It is also known as natural loading as it is the power loading at which reactive power is neither produced nor absorbed. The following equation is used to calculate surge impedance: $S I L = \frac{V_{L L}^{2}}{Z_{0}}$ $SIL=(V_(LL)^2)/Z_0$ , where:

$V_{L L}$ $V_(LL)$ = line-to-line voltage
$Z_{0}$ $Z_0$ = surge impedance
