What is an on load voltage regulating transformer? What are the advantages
First of all, let's talk about the definition: a transformer that can automatically adjust voltage with load is called an on load tap changer.

This definition is still very simple, the name given is its meaning. There are many manufacturers of dry-type transformers, and only we, a dry-type transformer manufacturer, can explain it to everyone. Please support us!

Now let's explain the advantages, which are three points in total, as follows:
① Can stabilize voltage.
Due to the constantly changing electricity load of the power grid, line losses and voltage drops also vary. If the load changes greatly, the grid voltage will not be stable. So the benefit of using on load tap changers is that their output voltage will automatically adjust with the load at any time, maintaining the grid voltage within a relatively stable range. Therefore, it can stabilize the voltage of regional power grids or key users within the allowable voltage deviation range. After being adjusted by transformer manufacturers like us, this advantage will have a more significant effect.


② Can save electricity.


For example, if the reactive power in the power grid is insufficient, the system voltage will decrease, which may cause load instability. At the same time, due to the low power factor, line loss will increase. Therefore, at this time, it is necessary to increase reactive power compensation to increase power factor, reduce line loss, and improve system voltage. This operation method requires the addition of reactive power compensation equipment, which means an increase in investment. Cost increase is definitely something that enterprises do not want to see. At this time, if an on load tap changer is used, the system voltage can be stabilized, thereby relatively increasing the power factor, reducing line loss, and reducing investment in reactive power compensation equipment. This is the process and advantage of cost savings.

③ Contact the power grid.


Connecting several power grids together is of great significance for power supply reliability, economic operation, and flexible scheduling. Connecting the power grid through an on load tap changer can increase the grid voltage during peak electricity consumption and reduce it during low electricity consumption, thereby ensuring voltage quality.
