Step 2: Evaluating the Configuration with Calculations Section 3-5
Group 1:(20 × 0.015 + 2 × 0.005) × 0.885 = 0.2744 V
Group 2:(10
× 0.015 + 1 × 0.005) × 1.1 = 0.1705 V
Total voltage drop = 0.2744 + 0.1705 = 0.4449 V
≤ 0.65 V
In this case, formula 2 is satisfied on the left side.
b) System 2 (Right Side)
Group 3:(10
× 0.015 + 1 × 0.005) × 0.5 = 0.0775 V
Group 4:(30
× 0.015 + 2 × 0.005) × 0.85 = 0.391 V
Total voltage drop = 0.0775 + 0.391 = 0.4685 V
≤ 0.65 V
In this case, formula 2 is satisfied on the right side.
