AUTO TRANSFORMER STARTER (ATS)

AUTO TRANSFORMER STARTER (ATS)

We design & manufacture highly efficient Autotransformer Starter panel of the desired parameters as specified by our customers. The main purpose of this panel is to limit the starting current of the pumps or motors by using a three phase Autotransformer to reduce the initial stator applied voltage. This is achieved by automatic selection of different tapings across the auto transformer.

Advantages

  1. Auto Transformers are used to Limit Inrush Current & starting Torque in AC Motors under Starting OR Locked Condition.
  2. To Eliminates the Problems associated with Line Voltage Drop, resulting from High inrush Current in AC Motors, it is recommended to use Reduced Starting Voltage.
  3. The Motor Starting Auto Transformers are designed with Taps @ 60-70-80% of Nominal Line Voltage.

Applications

Auto Transformer Starter is best suited when maximum reduction of inrush current is desired OR motor requires longer acceleration time with good starting torque for following applications.

 

Pumps : Submersible pumps, Boosting pumps for water supply, Dewatering pumps in mines & Ports, Oil extraction pumps, Sewage pumps.
Mixers : Chemical industry, Food & beverage industry.
HVAC : Centralized air-conditioning, Chillers, Compressors.
Blowers/Fans : Ventilation & ID/FD applications
Extruders & Grinders : Oil mills, Solvent plants, Poultry feed plants.
Crushers : Paper mills, Sugar mills.

Features

  1. Easy installation
  2. Standard tappings are provided at 50%, 65% & 80% of the line voltage
  3. Leak proof CRCA MS sheet cabinet for containing the transformer cooling oil.
  4. Visual indication of oil provided outside the oil cabinet.
  5. Auto Transformers are used to Limit Inrush Current & starting Torque in AC Motors under Starting OR Locked Condition.
  6. To Eliminates the Problems associated with Line Voltage Drop, resulting from High inrush Current in AC Motors, it is recommended to use Reduced Starting Voltage.
  7. The Motor Starting Auto Transformers are designed with Taps @ 60-70-80% of Nominal Line Voltage.

Used In

  1. Oil/Gas/Chemical Plants
  2. Sewage Plants
  3. Processing Industries
  4. Agricultural Activities

We manufacture Auto transformer Starter panels with the parameters specified by our clients. This panel’s main purpose is to reduce the stator voltage to lower the starting current for motors or pumps. This is done by automatically selecting different tappings on the auto-transformer.
