How does a Current Transformer Work?
Current Transformer is used to measure current in Transmission lines. It is coupled magnetically with transmission lines and Transformer action takes place. Smaller current flows through C.T. which is proportional to line current. Read More »

How to Check Current on a Transformer
The design of a transformer determines its input and output voltages. Current ratings for transformers indicate the maximum amount of current the transformer can withstand. But the actual current going through it at any moment depends on th... Read More »

How to Make a Current Transformer
A current transformer is used to measure the current of a circuit into which an ammeter cannot be directly inserted. Transformers consist of two circuits linked with magnetizable material called a "core." Both circuits have a length that co... Read More »
