Wiring drawing
Transformer is one of the most important electrical equipment in power system which is similar to power transformer. It is also used to convert voltage or current of line. However, the purpose of power transformer converting voltage and current is to transfer electric energy, and the purpose of transformer converting voltage or current is to measure and monitor the voltage or current of the line. Generally speaking, if the capacity of power transformer is large, the variation error of voltage or current is also large. If the capacity of transformer is small, the variation of voltage or current is small. In the measurement line, the transformer used to convert current and supply power to current instrument and relay is called current transformer, and the transformer used to convert voltage and supply power to voltage instrument and relay is called voltage transformer.
