HT AVR Manufacturers

As the name speaks itself, these stabilizers are used to stabilize the voltage on 11KV or 22KV or 33KV Side itself i.e. before distribution transformer.

The fluctuating HT Voltage received from Electricity Authority is stabilized by the HT Stabilizer with accuracy of +1% and then fed to the transformer resulting in the stabilized LT Output within +1% accuracy.

Many People remain under the fear that stabilizeing voltage on HT Side is dangerous and requires more maintenance and highly skilled technician is required to do preventive maintenance of the same, but this is not true at all.

Rolling Contact type regulator used in it is the same as used in LT Stabilizer . servo Voltage Stabilizer and Microprocessor based controller are also same as in case of LT Servo Voltage Stabilizers.

Working Principle Of Voltage Stabilizaion On HT Side Indianservocontrols’s On Load Voltage Regulator :

Indianservocontrols’s On Load Stepless Automatic Voltage Regulator works with the principle of auto transformer , tapped continuously by means of rolling contact mechanism moved by Servo motor ( which receives signal from electronic controller to move clockwise or anticlockwise)for stabilising output voltage continuously.Correction of voltage is also possible by Raise / Lower Push Buttons ( i.e.Manual operation ) if electronic controller Starts malfunctioning.

If both Automatic and motorised controls fail , correction of voltage is possible by means of a Hand Wheel.
