Voltage Drop Calculation with Phasor Diagrams | Voltage Referred to Far End | Ex-14.1

This is lecture 3 of power system course. In this video, I explain Example 14.1 from VK Mehta’s Principles of Power System, focusing on how to calculate the voltage drop in an AC distribution system and how to draw the corresponding phasor diagram. The problem revolves around a single-phase AC distributor and involves loads at different distances, with the voltage referred to the far end of the circuit.
I walk you through each step of the calculation process, breaking down complex formulas into an easy-to-understand format, explained in Bangla. This makes it easier for both engineering students and those studying at the diploma level to grasp the concepts and apply them in real-life situations. The video covers:
AC Distribution Problem Overview
Introduction to the given problem and the key parameters like load currents, power factors, and distances along the distributor.
Voltage Drop Calculation
A detailed, step-by-step process to calculate the voltage drop across the AC distributor with loads at two points, referred to the far end.
Phasor Diagram Explanation
How to draw and analyze phasor diagrams to represent the relationship between voltage, current, and impedance, making it easier to visualize the problem.
Easy Approach for Students
I’ve simplified the steps to make this tutorial accessible to diploma students and anyone new to power system calculations, with all explanations provided in Bangla.
This video is perfect for those looking to understand AC distribution systems, learn how to calculate voltage drops, and effectively use phasor diagrams in power systems. Whether you’re an undergraduate, diploma student, or a professional, this detailed tutorial will help you master these important concepts.
