The function and working principle of voltage transformer

      The basic type of voltage transformer includes two sets of coils wound with wires, and they are inductively combined with each other. When an alternating current (with a known frequency) flows through one set of coils, an alternating voltage with the same frequency will be induced in the other set of coils, and the magnitude of the induced voltage depends on the coupling of the two coils and the magnetic alternating current. degree of chain.

      The voltage transformer is abbreviated as PT. Its working principle is very similar to that of a transformer. It is used to transform the voltage on the line. When measuring the large voltage of the alternating current, in order to be able to safely measure a transformer (connected to the input end of the transformer) in parallel between the live wire and the ground wire, the output end of the transformer is connected to a voltmeter, because the number of turns of the input coil is greater than             The number of turns of the output coil, so the output voltage is less than the input voltage, the voltage transformer is a step-down transformer.

The role of voltage transformer:

1. Convert the high voltage into a standard secondary voltage of 100V or lower in proportion to the use of protection, metering, and instrumentation devices.

2. The use of voltage transformers can isolate high voltages from electrical workers.

3. When the secondary load impedance decreases, the secondary current increases, so that the primary current automatically increases a component to satisfy the electromagnetic balance relationship between the primary and secondary sides.
