Are There Any Limitations On Transformer Capacity When Installing A Voltage Optimizer?

After voltage optimizer is connected to the grid, it will adjust the voltage level. This adjustment does not directly change the design value of the transformer's nominal capacity (capacity class). The transformer's capacity is usually determined by its coil design, materials, and cooling system; these parameters determine the maximum power and current it can carry.

If 3 phase voltage optimiser makes the voltage more stable and reduces voltage fluctuations, it may also alleviate the additional load on the transformer caused by overvoltage or voltage instability. Nevertheless, the transformer capacity itself will not automatically increase due to the installation of voltage optimizer 3 phase.
