Introduction to Current Transformers Part 1: What are CTs and why use them?

In this series, we will introduce the current transformer and will give an example where we would want to use a CT. We'll also look at polarity marks for CTs and talk about the current transformer ratio and how to relate primary current to secondary current. Then we will take three CTs and connect them to the WYE and delta connection. In the last, we will draw the current transformer model and show the voltage currents and impedance's that are associated with the CT model.
