A voltage transformer is a transformer with an iron core. It mainly consists of primary and secondary coils, iron core, and insulation. When a voltage U1 is applied to a primary winding, a magnetic flux is generated in the iron core φ, According to the law of electromagnetic induction, a secondary voltage U2 is generated in the secondary winding. Changing the number of turns of the primary or secondary winding can generate different primary and secondary voltage ratios, which can form voltage transformers with different ratios. A voltage transformer proportionally converts high voltage into low voltage, i.e. 100V. The primary side of the voltage transformer is connected to the primary system, and the secondary side is connected to measuring instruments, relay protection, etc; Mainly electromagnetic (capacitive voltage transformers are widely used), there are also non electromagnetic types such as electronic and optoelectronic.
