The auto-starters (using three auto transformers) can be used to start cage induction motor of the following type__________?
Correct answer: C. A. and B. both
- A. star connected only
- B. delta connected only
- C. A. and B. both
- D. none of the above
Explanation
An autotransformer starter can reduce the applied starting voltage for a cage motor regardless of whether its normal stator connection is star or delta. Therefore it can be used with both types of connection.
