The current transformer may have heard that it is a common device. The function is to convert a larger current through a certain variable ratio to a smaller two current, which is used for protection, measurement, and so on. If the current transformer, which is changed to 400/5, can convert the actual current of 400A into a current of 5A.
So what principle does this current transformer work on?
The principle of current transformer is based on the principle of electromagnetic induction. A current transformer consists of a closed core and a winding. The number of the primary winding turns its little string in the current need to measure the line, so it is often full of current flowing through the line, the two winding turns more, are connected in series with the appearance and maintenance of measuring circuit of current transformer in operation, the two side loop it from the beginning to the end is closed, thus measuring the appearance and maintenance of the loop impedance in series with the coil is very small, close to the operating state of short circuit current transformer. A current transformer is used to convert a large current from one side to a small current at the two side, and the two side is not open.
