Conductor loss reduction calculator

Conductor power saving is calculated as (I_old^2−I_new^2) × R. Use the stated system boundary and matching input units.

ΔP=(Iold2−Inew2)×R\Delta P = \left(I_{\text{old}}^{2} - I_{\text{new}}^{2}\right) \times R

Worked example

Given

  • IoldI_{\text{old}} = 400 A
  • InewI_{\text{new}} = 340 A
  • RR = 0.02 ohm
ΔP=(4002−3402)×0.02=888\Delta P = \left({400}^{2} - {340}^{2}\right) \times 0.02 = 888
