The basic structure of the voltage transformer is very similar to that of the transformer. It also has two windings, one is called the primary winding and the other is called the secondary winding. Both windings are mounted or wound around the iron core. There is insulation between the two windings and between the windings and the iron core, so that there is electrical isolation between the two windings and between the windings and the iron core. When the voltage transformer is running, the primary winding N1 is connected to the line in parallel, and the secondary winding N2 is connected to the instrument or relay in parallel. Therefore, when measuring the voltage on the high-voltage line, although the primary voltage is high, the secondary is low-voltage, which can ensure the safety of operators and instruments.
