Voltage Regulation of Alternator | Step-by-Step Numerical (Star Connected, 3-Phase)

🔌 Voltage Regulation of Alternator | Step-by-Step Numerical (Star Connected, 3-Phase) ⚡

In this video, I’ve explained a complete numerical problem on voltage regulation of a 3-phase alternator in a clear and exam-oriented way. This problem covers key concepts like open circuit test, short circuit test, synchronous impedance method, and how power factor affects regulation.

📘 Given Data:
• Line Voltage = 3300 V
• Full Load Current = 100 A
• Field Current (SC) = 5 A
• Open Circuit EMF = 900 V
• Armature Resistance = 0.8 Ω/phase
• Connection = Star

📊 What you will learn:
✔ How to calculate synchronous impedance
✔ Step-by-step voltage regulation calculation
✔ Difference between lagging and leading power factor
✔ Practical understanding for exams like diploma, B.Tech & competitive tests

⚡ Cases Covered:
1️⃣ 0.8 Power Factor Lagging
2️⃣ 0.8 Power Factor Leading

🎯 This video is perfect for students preparing for:
• Electrical Engineering exams
• Semester exams
• Competitive exams like GATE, SSC JE

👉 Watch till the end for full clarity and problem-solving approach!
