STEP 0: Pre-Calculation Summary

Formula Used

Fault Current = C Phase Voltage/Fault Impedance
I_f = V_c/Z_f
This formula uses 3 Variables

Variables Used

Fault Current - (Measured in Ampere) - The fault current is the electrical current which flows through a circuit during an electrical fault condition.
C Phase Voltage - (Measured in Volt) - C phase Voltage is defined as the voltage of c-phase.
Fault Impedance - (Measured in Ohm) - Fault Impedance is a measure of the resistance and reactance in an electrical circuit that is used to calculate the fault current that flows through the circuit in the event of a fault.

STEP 1: Convert Input(s) to Base Unit

C Phase Voltage: 17.2 Volt --> 17.2 Volt No Conversion Required
Fault Impedance: 1.5 Ohm --> 1.5 Ohm No Conversion Required
