Generally, the primary winding of a single-phase voltage transformer is connected to the high-voltage side of the circuit under test to induce high-voltage signals; while the secondary winding is connected to measuring instruments or protective equipment to output corresponding low-voltage signals. By converting the ratio, the single-phase voltage transformer can convert the high-voltage signal into a proportional low-voltage signal to facilitate the use of measurement and protection equipment.
The main features of single-phase voltage transformers include:
High precision: Single-phase voltage transformers have high measurement accuracy and can accurately output low-voltage signals proportional to the voltage in high-voltage circuits.
High reliability: Made of high-quality materials and advanced technology, it has strong anti-interference ability and stability, ensuring the reliability and stability of the equipment.
Compact structure: It usually adopts lightweight design and compact structure, takes up less space and is easy to install and wire.
Various installation methods: Single-phase voltage transformers can be installed in different installation methods according to needs, such as plug-in type, fixed type, etc., to adapt to different power system layouts and needs.
High insulation level: It has good insulation performance and can ensure safe operation in high voltage environments.
