How Calculate Cable Size ((better)) Access

[ V_d = \frac2 \times L \times I \times R_cable1000 ] Where ( R_cable ) = resistance in Ω/km from cable data.

19.53 V > 6.9 V → → increase cable size. how calculate cable size

[ I = \fracPV ]

[ V_d = \frac\sqrt3 \times L \times I \times (R\cos\phi + X\sin\phi)1000 ] [ V_d = \frac2 \times L \times I

[ I = \fracP\sqrt3 \times V \times \textPower Factor ] how calculate cable size

( 0.03 \times 230 = 6.9 \text V )
