Line losses

Loop resistance, power and energy losses, and transmission efficiency.

Electrical engineering

Single-phase line loop resistance

R = 2ρL / S→Electrical engineering

Three-phase line power loss

Pₗ = 3I²ρL/S→Electrical engineering

Line energy loss

Wₗ = Pₗt / 1000→Electrical engineering

Line transmission efficiency

η = Pₙ / (Pₙ + Pₗ) × 100%→
