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

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Voltage Overhead AC = (sqrt(2)*Power Transmitted)/(3*cos(Phase Difference))
V_m = (sqrt(2)*P)/(3*cos(Φ))
This formula uses 2 Functions, 3 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 Overhead AC - (Measured in Volt) - Maximum Voltage Overhead 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 defined as the product of current and voltage phasor in a overhead ac line at the receiving end.
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.

STEP 1: Convert Input(s) to Base Unit

Power Transmitted: 890 Watt --> 890 Watt No Conversion Required
Phase Difference: 30 Degree --> 0.5235987755982 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_m = (sqrt(2)*P)/(3*cos(Φ)) --> (sqrt(2)*890)/(3*cos(0.5235987755982))

Evaluating ... ...

V_m = 484.454638017117

STEP 3: Convert Result to Output's Unit

484.454638017117 Volt --> No Conversion Required

FINAL ANSWER

484.454638017117 ≈ 484.4546 Volt <-- Maximum Voltage Overhead AC
