Vertical Rolling Contact Voltage Stabilizer

Vertical rolling contact voltage stabilizer comprises of Voltage Regulator and an Auto Transformer.

Rolling Spring Carbon moves on vertical regulator coil with help of Servo AC Motor.

The output voltage depends upon this movement of carbon.

The size of this type of stabilizer is smaller as compared to Varic type Servo Stabilizer.
