Energy saving benefits: temperature affects Conductor Impedance and voltage drop, resulting in energy consumption and electricity (fee) increase.
△W=I ² RT
Δ w = loss
I = current R large ↑ △ w ↑ kwh ↑
R = impedance r large ↓ △ w ↓ kwh ↓
T = time
KWh = electric degree
At the same current, the conductor impedance directly affects the loss of the bus, and the cumulative kwh x tariff will lead to the change of energy consumption or energy saving.
