2 8838Why different types of connection in transformers are used? (star/star,star/delta,delta/star,delta/delta)Why we are only taking in consideration of star/delta type transformers? if only star/delta is good in practice where doses other type of transformers are used? Note: i want to know place of using different types of transformers other than Star/delta type with brief description.
