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

STEP 0: Pre-Calculation Summary

Formula Used

Root Mean Square Voltage = Power Transmitted/(3*cos(Phase Difference))
V_rms = P/(3*cos(Φ))
This formula uses 1 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)

Variables Used

Root Mean Square Voltage - (Measured in Volt) - Root Mean Square Voltage is the square root of the time average of the voltage squared.
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_rms = P/(3*cos(Φ)) --> 890/(3*cos(0.5235987755982))

Evaluating ... ...

V_rms = 342.561159719178

STEP 3: Convert Result to Output's Unit

342.561159719178 Volt --> No Conversion Required

FINAL ANSWER

342.561159719178 ≈ 342.5612 Volt <-- Root Mean Square Voltage
