To calculate impedance enter your Voltage and PFC values. PFC Calculation Parameters: Impedance measured in Ohms. Voltage measured in Volts. PFC measured in kA. How to calculate impedance Impedance = V ÷ I Voltage (V) ÷ Current (I) = Impedance (Ohms)Calculate...
Before a fault current calculation can be performed, all of the possible sources of current must be identified. There are four possible sources of short-circuit fault current: On-site electric generators: These are close and the fault current is only limited by the impedance of the generator it...
At the main switchboard, the fault current is further reduced because of the additional cable impedance of the consumer’s mains. At the distribution board, the fault current is further decreased by the cable impedance of the submains. Fault calculation methods for industrial and ...

Fault calculation involves determining the faultcurrentin a power system. It typically includes three main steps. Choice of impedance rotations. Reduction of complicated electrical power system network to single equivalent impedance. Electrical fault currents and voltages calculation by using symmetrical compo...
none of the above references provide an analytical calculation method for DC fault current. Therefore, the DC fault equivalent circuits of the HC-HVDC system are proposed in this paper. Furthermore, the analytical short-circuit current expressions of the HC-HVDC system are analyzed using the Lapla...
