STEP 1: Convert Input(s) to Base Unit

Power Transmitted: 890 Watt --> 890 Watt No Conversion Required
Resistivity: 1.7E-05 Ohm Meter --> 1.7E-05 Ohm Meter No Conversion Required
Length of Overhead AC Wire: 10.63 Meter --> 10.63 Meter No Conversion Required
Line Losses: 8.23 Watt --> 8.23 Watt No Conversion Required
Voltage Overhead AC: 180 Volt --> 180 Volt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K = (4*(P^2)*ρ*L)/(P_loss*(V_ac^2)) --> (4*(890^2)*1.7E-05*10.63)/(8.23*(180^2))

Evaluating ... ...

What is the value of maximum voltage and volume of conductor material in 1-phase 3-wire system?

The volume of conductor material required in this system is (5/8)cos²θ times that of 2-wire d.c.system with the one conductor earthed. The maximum voltage between conductors is 2v_m so that r.m.s. value of voltage between them is √2v_m.
