Load Current(Single-Phase Two-Wire Mid-Point Earthed) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Current Overhead AC = Power Transmitted/(sqrt(2)*Maximum Voltage Overhead AC*cos(Phase Difference))
I = P/(sqrt(2)*V_m*cos(Φ))
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 Overhead AC - (Measured in Ampere) - Current Overhead AC is defined as the current flowing through the overhead ac supply 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.
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.
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
Maximum Voltage Overhead AC: 62 Volt --> 62 Volt No Conversion Required
Phase Difference: 30 Degree --> 0.5235987755982 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I = P/(sqrt(2)*V_m*cos(Φ)) --> 890/(sqrt(2)*62*cos(0.5235987755982))

Evaluating ... ...

I = 11.7206767262206

STEP 3: Convert Result to Output's Unit

11.7206767262206 Ampere --> No Conversion Required

FINAL ANSWER

11.7206767262206 ≈ 11.72068 Ampere <-- Current Overhead AC
