Fault Current Components (IEC 60909)
Peak Make Current:
ip = √2 × Ik" × (1.02 + 0.98 × e-3/XR)
Maximum instantaneous current during first half-cycle
DC Time Constant:
τ = X / (2πfR) = XR / (2πf)
DC Component:
idc(t) = √2 × Ik" × e-t/τ
Decays exponentially with time constant τ
Total Fault Current:
i(t) = √2 × Ik" × sin(2πft) + idc(t)
