Servo Voltage Stabilizers

Nowadays voltage stabilizers have become mandatory for residential, office, commercial and industrial use. Voltage variation & fluctuation is common problem in every industry. Voltage variation manifests in many different ways due to low voltage or sags. Servo voltage stabilizers increase or decrease the voltage levels and ensure that the proper range of voltage is supplied at the end. We are having Range of 10 KVA to 5000 KVA. GNT make Servo voltage stabilizers resolves 99% of voltage problems automatically and ensures a steady voltage supply round the clock. They are known for their rugged built and maintenance free performance.

Description of GNT Servo Voltage Stabilizer

Linear, plus/minus type vertical Rolling Contact Voltage Regulator
In our Regulator we are using heavy section of electrolytic rectangular copper strip instead of copper wire to minimize the losses & increase the efficacy of equipment. We are also using self-lubricating Carbon Roller assemblies instead of ordinary carbon brushes which offers more reliability and trouble free performance of the equipment.
Double Wound Buck/Boost type Series Transformer
In our Buck/Boost transformer we are using CRGO lamination to minimize iron losses and coils of Buck/Boost Transformer are wound with heavy section of multi strips electrolytic copper to minimize copper losses for getting better efficiency of the equipment.
Electronic Control Circuit and meter panel
GNT Servo voltage stabilizer consists of very simple electronic control circuit for monitoring and controlling voltage, repair & maintenance of which is very easy. The regulator and Buck/Boost transformer are oil cooled, housed in same or separate sheet steel tanks. Radiators are provided for effective cooling. The coils of voltage regulator & Buck/Boost Transformers are vacuum impregnated and oven dried as per IS
