WebIn the previous chapter, we saw how to calculate the symmetrical fault current. This is important from the rms heating point of view, but for distribution switchgear engineers, the asymmetrical current is of much greater importance for a number of reasons. The rate of rise of current is higher under symmetrical fault conditions but the peak ... WebMay 22, 2024 · A very common application of symmetrical components is in calculating currents arising from unblanced short circuits. For three-phase systems, the possible unbalanced faults are: Single line-ground, Double line-ground, Line-line. These are considered separately.

WebA specification may give one value in kA rms and one value in MVA as: Isc = 19 kA rms or 350 MVA at 10 kV. If we calculate the equivalent current at 350 MVA we find, Isc = 350 / (1.73 x 10) = 20.2 kA rms. The difference depends on how we round up the value and on local habits. The value 19 kA rms is probably the most realistic. WebStep 6.
