Maximum Voltage using Load Current (3 Phase 4 Wire US) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Voltage Underground AC = (sqrt(6)*Power Transmitted)/(3*cos(Phase Difference)*Current Underground AC)
V_m = (sqrt(6)*P)/(3*cos(Φ)*I)
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

Maximum Voltage Underground AC - (Measured in Volt) - Maximum Voltage Underground AC is defined as the peak amplitude of the AC voltage supplied to the line or 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.
Phase Difference - (Measured in Radian) - Phase Difference is defined as the difference between the phasor of apparent and real power (in degrees) or between voltage and current in an ac circuit.
Current Underground AC - (Measured in Ampere) - Current Underground AC is defined as the current flowing through the overhead ac supply wire.

STEP 1: Convert Input(s) to Base Unit

Power Transmitted: 300 Watt --> 300 Watt No Conversion Required
Phase Difference: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Current Underground AC: 9 Ampere --> 9 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_m = (sqrt(6)*P)/(3*cos(Φ)*I) --> (sqrt(6)*300)/(3*cos(0.5235987755982)*9)

Evaluating ... ...

V_m = 31.4269680527354

STEP 3: Convert Result to Output's Unit

31.4269680527354 Volt --> No Conversion Required

FINAL ANSWER

31.4269680527354 ≈ 31.42697 Volt <-- Maximum Voltage Underground AC
