WebTo calculate tA, first calculate the arc fault current ( IA) from the following equation: log (I A) = K + 0.662log (I bf )+0.0966V+0.000526 (G) + 0.5588 (V)log (I bf )-0.00304 (G)log (I bf) Where: IA: is the arc fault current. Ibf: is the bolted short circuit current (3-phase symmetrical rms kA). G: is the gap between conductors or buses.
