L. T. Automatic Voltage Regulator Servo Stabilizers
RANGE : Up to 10000 KVA
General Information
Electricity is the heart beat of any industry/office and Transformer is the heart of the Company but today scenario hardly any industry receive Quality Electric Supply (Constant Voltage) due to long transmission line, imbalance between supply & demand of power & poor infrastructure. Higher & Lower voltages above rated voltage adversely affect the life of the equipment and consume more power thus increases the burden on the balance sheet of the company. So to resolve the problem of voltage fluctuation we have automatic voltage stabilizer, L.T. voltage stabilizer before the load point installed.
Application
These L T -Automatic Voltage Regulators are widely used in industries of various sector for
getting a stable input voltage.
Our products are widely used in the following areas:
Advantages
- Higher current produces higher losses in electrical motors which causes premature failure of winding.
- These higher losses of electric motors also increase the losses of cables, switches, transformers & other associated equipments.
- For smooth continuous operation of motors, over load relays are usually set at 20% higher setting

- Plastic Processes
- 1. In Low Tension-Automatic Voltage Regulators, there are helical coils mounted on a conventional laminated core
- 2. Carbon rollers goes along the length of the coil track & are assembled on a fiber glass carrier board
- 3. The rollers are connected to the electric output terminals
- 4. Parallel connection of compensating winding near the regulating coil is done
- 5. The connection between the windings and regulating coils is short circuited so as to reduce the effect of core-flux fringing
- 6. It keeps the reactance of the regulator constant at any position of the rolling contact
