Voltage fluctuation is a common phenomenon in every part of the country. In spite of the best efforts, no state electricity board can ensure the constant voltage to the customer because of long and inadequate distribution lines and irregular load pattern on Distribution Transformers. Automatic Voltage Controller (Stabilizer) is an equipment to obtain constant voltage from fluctuating supply system. The industrial units running round the clock usually face the problem of low and high voltage. 90% of industrial load is of motors. Electric motors draw considerably high current at low and high voltage.

Description of Global’s Servo Controlled Automatic Voltage Controller

GLOBAL ENERGY SAVER Servo stabilizer primarily consists of the following:

1. Linear, plus/minus type Vertical Rolling Contact Voltage Regulator

In our regulator we are using heavy section of electrolytic rectangular cupper strips instead of copper wire to minimize the losses & increase the efficiency 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.

2. 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.

3. Electronic Control Circuit & MeterPanel.

Our Automatic Voltage Controller consists of very simple electronic circuit for monitoring and controlling voltage, repair & maintenance of which is very easy.
