Automatic voltage controller increases system efficiency and power quality by automatically monitoring and controlling busbars, transformers and other devices. Some of the common voltage controller devices include stabilizers, regulators, electroplating rectifiers, etc. On a power distribution system experiencing varying loading conditions, this type of sophisticated substation automation application can effectively maintain a steady transformer secondary voltage within preset limits.

The high capacity automatic voltage controllers manufactured in our unit are supervised by a team of qualified and experienced engineers. Our chief goal is to satisfy our customers by manufacturing quality products.

High current on a load affects electrical motors (smaller capacity motors upto 7.5 H.P) and devices in the following ways:

• High current causes premature failure of winding in electrical motors leading to their damage or higher losses.
• The higher losses of electrical motors in turn leads to damage of cables, switches, transformers and other associated equipment.
• In order to ensure smooth and continuous working of electrical motors, overload relays are generally set at 20% higher setting.

With the installation of the stabilizer and maintaining 390/400 volts, the motor will operate smoothly. It will draw 15 to 20% lesser current and correspondingly the relay setting can be reduced by 15 to 20%. When single phasing occurs, the relay will trip in 40 to 50 seconds. The motor can withstand the high current during this period and will be safe. Also, the switchgears, relays, contactors etc. incorporated with the motor will be safe.


Types of Automatic Voltage Controllers

• Balanced Type Automatic Voltage Controller
• Automatic Voltage Controller with Bye-pass arrangement
• Unbalanced Type Automatic Voltage Controller
• Automatic Voltage Controller with Isolation

Servo Stabilizer is an automatic voltage regulator, which primarily consists of the following features :

• Linear, plus / minus type vertical rolling contact voltage regulator
  For making these regulators, we use heavy section of electrolytic grade rectangular copper strip instead of copper wire in order to minimize the losses & increase the efficiency of equipment. We also employ self lubricating Carbon Roller Assemblies instead of ordinary Carbon Brushes that offers more reliability and trouble free performance of the equipment.
• Double wound buck / boost type series transformer
  In our Buck / Boost transformer, we make use of CRGO lamination to reduce iron losses. The coils of Buck / Boost transformer are wound with heavy section of multi strips electrolytic copper to minimize copper losses to get better efficiency of the equipment.
• Electronic control circuit and meter panel
  Automatic Voltage Controller usually consists of very simple electronic control voltage circuit for monitoring and controlling voltage, repair and maintenance of which is very easy. The regulator and Buck / Boost transformer are oil cooled, placed in same or separate sheet steel tanks. These devices are provided with radiators for effective cooling. The coils of voltage regulators & Buck / Boost Transformers are vacuum impregnated and oven dried as per IS.
