    Conversion using the Short Circuit Current Calculation Formula

    Short-circuit current computations for electrical systems rely on the values of impedance alongside voltage strength and fault position. The general equation to find short-circuit current in an AC system looks as follows:

    This formula is typically used for DC circuits or in simplified AC circuit models where the only significant resistance is the short-circuit resistance. In real AC systems, the impedance (which includes both resistance and reactance) is more commonly used, but for DC systems, this formula works well:

    Ishort = VRshort

      Where:

    • Ishort = is the short-circuit current (in Amperes, A)
    • V = is the applied voltage (in Volts, V)
    • Rshort = is the resistance of the fault path or the short-circuit path (in Ohms, Ω)
