ATS TRANSFORMERS

ATS Transformers

Auto Transformer's are utilized to Limit Inrush Current and beginning Torque in AC Motors under Starting OR Locked Condition

• Up to 1500 KW rating
• An auto-Transformer starter makes it possible to start squirrel-cage induction motors with reduced starting current, as the voltage across the motor is reduced during starting.
• The motor starts at the voltage reduced by the transformer, with a correspondingly smaller current.
• Which means the feeding current in comparison to direct starting would be reduced by the square of the transformer voltage ratio; nevertheless, it is in most cases noticeably higher, as it also covers the relatively high transformer losses
