Technical Field

The invention relates to a high-voltage current transformer with an error measurement function.

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 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. The current transformer can generate heat during working, and the heat is not dissipated to influence the measurement accuracy.
