B-Phase Current (LLGF) Solution

STEP 0: Pre-Calculation Summary

Formula Used

B Phase Current = Fault Current-C Phase Current
I_b = I_f-I_c
This formula uses 3 Variables

Variables Used

B Phase Current - (Measured in Ampere) - B phase Current is defined as the current flowing through the b-phase in open conductor fault.
Fault Current - (Measured in Ampere) - The fault current is the electrical current which flows through a circuit during an electrical fault condition.
C Phase Current - (Measured in Ampere) - C phase current is the current that flows into the c-phase in open conductor fault.

STEP 1: Convert Input(s) to Base Unit

Fault Current: 4.27 Ampere --> 4.27 Ampere No Conversion Required
C Phase Current: 3.9 Ampere --> 3.9 Ampere No Conversion Required
