Basic Concepts Of Current Transformers

- Oct 25, 2018-

The principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. It has a small number of winding turns, strung in the line that needs to be measured, so it often has all the current of the line flowing through, more than two winding turns, concatenated in the measuring instrument and protection circuit, the current transformer in the work, its two circuit is always closed, so the measurement instrument and Protection Loop series Coil impedance is very small, The working state of the current transformer is close to short circuit.
