Stabilizers Oil Cooled Roller Stabilizers

Automatic Voltage Stabiliser is necessary for smooth functioning

In spite of best efforts, Electricity board cannot ensure constant voltage to the consumer because of the long and inadequate distribution lines and irregular load patterns on distribution transformers. Generally, voltage is low during day time and high during night. Moreover on holidays, peak hours, rainy days and when agricultural and Industrial loads are switched off, the voltage rises sharply which is potentially dangerous to cause serious damages to your electrical appliance.

Higher voltages lead to higher current & lead to

If you install a servo stabiliser, you maintain a voltage of 390-400V & motor will operate smoothly consuming 15-20% lesser current accordingly relay settings can be reduced by 15-20%.

We at TechnoVision manufacture Servo Stabilisers as per IS: 9815
