उत्पाद विवरण

Since our inception in the year 2013, we are affianced in offering supreme quality Automatic Voltage Regulator. We manufacture this AVR at our advanced production set up using high grade tested raw materials and advanced machinery. This AVR is extensively used by our clients at running stations for automatic stabilization of voltage in order to protect the installed electrical units at various places from voltage fluctuation. अधिकover this LT AVR is available to our clients at very affordable prices.

Features of Automatic Voltage Regulator(AVR) :

• Rugged design
• Strong construction
• Easy to operate
• Noise less operation
  

Many state electricity boards have tried and failed to provide constant voltage to the customer. The reasons why this could not be achieved till now are long, inadequate distribution lines and irregular load pattern on distribution transformers. Everyone must have noticed that the voltage is low during day time and high during night time. Not only this irregularity, voltage rises sharply on rainy days,  holidays, peak hours, and times when agricultural and Industrial load is switched off; all this is dangerous.

The electric motors (particularly smaller capacity motors upto 7.5 H.P.) are affected by this higher current in different ways; which are:

• Premature failure of winding is caused by the sudden higher current
• The loss of electric motor increases the loss of attached accessories and systems, like wires, switches, transformers, etc.
• To ensure smooth and continuous motor operations,  set over load relays at 20% higher setting.

With the stabilizer installation and 390/400 volts maintenance, one can allow smooth operation of motor. It will draw 15 - 20% lesser current and could reduce the the relay setting by 15 - 20%. In case of single phasing, within 40 - 50 seconds the relay will trip. For such a minimum time span, any motor can withstand the high current and will operate safely. Not just the motor, but all relays, switchgear, etc., incorporated with it will be safe.

L.T. AVR are installed in all running units with both, L.T. and small H.T. Connections. These can be manufactured for balance input voltage, unbalanced voltage and unbalanced load.

Technical Advantages:

• Undistorted output characteristics
• Moving parts on L.T. side and its mass is only few Ib-inch torque
• Energy savings
• High efficiency and minimum no-load losses
• Simplicity and flexibility of design
• On load stepless Voltage variation
• Long service life
• Low Replacement Cost

The edge of  rectangular conductors are wounded with regulating coils, so as to give high mechanical strength compared to other designs.
