Background
The current transformer is an instrument for measuring by converting a large primary side current into a small secondary side current according to the electromagnetic induction principle. The current transformer is composed of a closed iron core and a winding. The primary side winding of the transformer has few turns and is connected in a circuit of the current to be measured. Therefore, all current of a line always flows through the current transformer, the number of turns of the secondary side winding is large, the secondary side winding is connected in series in the measuring instrument and the protection loop, and the secondary side loop of the current transformer is always closed when the current transformer works, so that the impedance of the series coil of the measuring instrument and the protection loop is very small, and the working state of the current transformer is close to a short circuit. The current transformer converts a large current on the primary side into a small current on the secondary side for measurement, and the secondary side can not be opened. Current transformers can be broadly classified into two types according to their uses: current transformer for measurement (or measurement winding of current transformer): and in the normal working current range, providing current information of the power grid for devices such as measurement and metering devices. Protective current transformer (or protective winding of current transformer): and under the power grid fault state, providing power grid fault current information for devices such as relay protection devices and the like.
