Voltage transformer is a special transformer, its main function is to convert high voltage into standard, low voltage, in order to measure and protect electrical equipment. Its working principle and characteristics are as follows:

1. working principle

The working principle of the voltage transformer is similar to that of the transformer, which uses the principle of electromagnetic induction to realize the conversion of voltage. A high voltage is applied to the primary winding, an induced electromotive force is generated by electromagnetic induction, and a low voltage is output in the secondary winding. This process does not change the current in the circuit to ensure the accuracy of the measurement and the safety of the system.

2. features

1. Strong insulation performance: The working characteristic of the voltage transformer is its high insulation strength requirement, because it involves the conversion and measurement of high voltage, and the safety of operators and equipment must be guaranteed.

2. Output voltage stability: Because the voltage transformer adopts the principle of electromagnetic induction, its output voltage is stable and the measurement accuracy can be guaranteed.

3. Strong load capacity: The voltage transformer can carry a large load, even under high load conditions, it can ensure the accuracy of measurement.

4. High accuracy: Modern voltage transformers adopt advanced manufacturing technology and materials, and their accuracy is very high, which can meet the measurement needs of various electrical equipment.

5. Compact structure: The voltage transformer is compact in structure, easy to install, and can save space.

6. Safe and reliable: Due to its working characteristics in high voltage environment, the voltage transformer must have strict safety protection measures to ensure its stable operation and personnel safety in high voltage environment.

Widely used: Voltage transformers are widely used in power systems, industrial automation, or in the field of new energy.

In general, voltage transformers play a vital role in power systems. It can not only be used for voltage measurement of electrical equipment, but also provide overload protection to ensure the stable operation of the power system. In addition, due to its high accuracy, safety and reliability, and wide application, voltage transformers are widely used in all walks of life. Understanding the working principle and characteristics of voltage transformers is very important for electrical engineers and power system operators.
