Load Current Per Phase (3-Phase 3-Wire US) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Current underground DC = (sqrt(6)*Power Transmitted)/(3*Maximum Voltage*cos(Theta))
C₁ = (sqrt(6)*P)/(3*V_m*cos(θ))
This formula uses 2 Functions, 4 Variables

Functions Used

cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
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 underground DC - (Measured in Ampere) - Current underground DC is defined as the current flowing through the overhead ac supply wire.
Power Transmitted - (Measured in Watt) - Power Transmitted is the amount of power that is transferred from its place of generation to a location where it is applied to perform useful work.
Maximum Voltage - (Measured in Volt) - Maximum Voltage the highest voltage rating for electrical devices.
Theta - (Measured in Radian) - Theta is an angle that can be defined as the figure formed by two rays meeting at a common endpoint.

STEP 1: Convert Input(s) to Base Unit

Power Transmitted: 300 Watt --> 300 Watt No Conversion Required
Maximum Voltage: 60 Volt --> 60 Volt No Conversion Required
Theta: 30 Degree --> 0.5235987755982 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C₁ = (sqrt(6)*P)/(3*V_m*cos(θ)) --> (sqrt(6)*300)/(3*60*cos(0.5235987755982))

Evaluating ... ...

C₁ = 4.71404520791032

STEP 3: Convert Result to Output's Unit

4.71404520791032 Ampere --> No Conversion Required

FINAL ANSWER

4.71404520791032 ≈ 4.714045 Ampere <-- Current underground DC
