What is on-load voltage regulation of transformers?(Part 1)

On-load voltage regulation refers to adjusting the output voltage by adjusting the tap changer of the transformer when the transformer is operating under load, thereby changing the turns ratio of the transformer. This article will introduce in detail the advantages of on-load voltage regulation of transformers.

●Maintain voltage stability

On-load voltage regulation can automatically adjust the output voltage of the transformer when the load changes, so that it remains within a relatively stable range. This is crucial for ensuring the normal operation of various electrical equipment in the power system. For example, in industrial production, for some equipment with high voltage requirements, if the voltage fluctuates greatly, it may affect the performance and lifespan of the equipment. On-load voltage regulation transformers can effectively solve this problem and provide users with a stable power supply.

●Improve power supply quality

On-load voltage regulation allows users to adjust the output voltage according to actual needs to meet the voltage requirements of different users. This helps improve power supply quality and reduce the impact of voltage deviation and voltage fluctuation on users. At the same time, on-load voltage regulation can also quickly adjust the voltage and restore the normal operation of the system when there is a fault in the power system.

●Enhance system flexibility

On-load voltage regulation transformers can flexibly adjust the output voltage under different operating conditions to adapt to changes in the power system. For example, when the grid load increases, the output voltage can be appropriately increased to meet the demand for load growth; when the grid load decreases, the output voltage can be reduced to improve the operating efficiency of the system.

In Summary

In conclusion, on-load voltage regulation of transformers is an important voltage regulation method. It can automatically adjust the output voltage under load, maintain voltage stability, improve power supply quality, and enhance system flexibility. In the next article, we will introduce in detail the disadvantages of on-load voltage regulation.
