2. Major Components

The 250KVA three phase voltage stabilizer is mainly made of the following parts:


Transformer: this part plays an important role in compensating the voltage when the voltage is not stable.


Copper column: copper column helps regulate the voltage automatically.


Carbon brush: by co-working with copper column, the carbon brush also helps regulate the voltage at 380V or certain voltage.


Circuit board: this part is one of the major parts because it controls the whole circuit.


Chain drive: this part facilitates the movement of the carbon brush, and thus facilitating voltage regulation.
