C-Phase Current using Fault Impedance (LLF) Solution

STEP 0: Pre-Calculation Summary

Formula Used

C Phase Current = (C Phase Voltage-B Phase Voltage)/Fault Impedance
I_c = (V_c-V_b)/Z_f
This formula uses 4 Variables

Variables Used

C Phase Current - (Measured in Ampere) - C phase current is the current that flows into the c-phase in open conductor fault.
C Phase Voltage - (Measured in Volt) - C phase Voltage is defined as the voltage of c-phase.
B Phase Voltage - (Measured in Volt) - B phase Voltage is defined as the voltage of b-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.
