Sending End Angle using Sending End Power (STL) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sending End Phase Angle = acos(Sending End Power/(Sending End Voltage*Sending End Current*3))
Φ_s = acos(P_s/(V_s*I_s*3))
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)
acos - The inverse cosine function, is the inverse function of the cosine function. It is the function that takes a ratio as an input and returns the angle whose cosine is equal to that ratio., acos(Number)

Variables Used

Sending End Phase Angle - (Measured in Radian) - Sending End Phase Angle is the difference between the phasors of current and voltage at thee sending end of a short transmission line.
Sending End Power - (Measured in Watt) - Sending End Power is defined as the power at receiving end of a short transmission line.
Sending End Voltage - (Measured in Volt) - Sending End Voltage is the voltage at the sending end of a short transmission line.
Sending End Current - (Measured in Ampere) - Sending End Current is defined as the amount of current injected into a short transmission line from the source or injectors.

STEP 1: Convert Input(s) to Base Unit

Sending End Power: 4136 Watt --> 4136 Watt No Conversion Required
Sending End Voltage: 400 Volt --> 400 Volt No Conversion Required

What are losses of short transmission lines?

Short transmission lines incur losses primarily due to conductor resistance, dielectric losses in insulation, and leakage losses. Conductor resistance leads to I²R losses, while dielectric losses occur from the insulating materials. Leakage losses stem from the electric field extending beyond the line, dissipating energy.
