Why Do Current Transformers (CTs) Saturate? | Explained

Why does a Current Transformer (CT) saturate? You'll learn: 🔹 How a CT works — the role of the iron core, primary and secondary windings 🔹 What happens inside the CT during normal operation vs fault conditions 🔹 How magnetic dipoles and the B-H curve explain CT saturation 🔹 Why flux change, not flux itself, is key to secondary current generation 🔹 The physics behind saturation — made simple and visual This is more than just an explanation — it’s about understanding what’s really going on inside a CT so you can make better decisions in design, protection, and diagnostics. Whether you're a power engineer, protection specialist, or controls engineer, this is a concept you need to grasp. 📌 Don't forget to like 👍, subscribe 🔔, and share with fellow engineers who value deep understanding. 💬 Got questions or suggestions for future videos?
