STEP 0: Pre-Calculation Summary
Formula Used
Maximum Voltage Underground AC = (sqrt(6)*Power Transmitted)/(3*cos(Phase Difference)*Current Underground AC)
Vm = (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
Vm = (sqrt(6)*P)/(3*cos(Φ)*I) --> (sqrt(6)*300)/(3*cos(0.5235987755982)*9)
Evaluating ... ...
