Load Current using Area of X-Section(DC 3-Wire) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Current Overhead DC = sqrt(Area of Overhead DC Wire*Line Losses/(Resistivity*Length of Wire DC))
I = sqrt(A*P_loss/(ρ*L))
This formula uses 1 Functions, 5 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Current Overhead DC - (Measured in Ampere) - Current Overhead DC is defined as the current flowing through the overhead ac supply wire.
Area of Overhead DC Wire - (Measured in Square Meter) - Area of Overhead DC Wire is defined as the cross-sectional area of the wire of an overhead DC supply system.
Line Losses - (Measured in Watt) - Line Losses is defined as the total losses occurring in an Overhead DC line when in use.
Resistivity - (Measured in Ohm Meter) - Resistivity is the measure of how strongly a material opposes the flow of current through them.
Length of Wire DC - (Measured in Meter) - Length of Wire DC is the total length of the wire from one end to other end.

STEP 1: Convert Input(s) to Base Unit

Area of Overhead DC Wire: 0.65 Square Meter --> 0.65 Square Meter No Conversion Required
Line Losses: 0.74 Watt --> 0.74 Watt No Conversion Required
