10 13854In a 11000/440 V transformer, when any one phase of 11 KV supply fails (ie., single phasing), what happens to the secondary voltage and why?
3 206421KVA transformer of different frequencies of 50hz,100hz,500hz&1000hz. which one of these transformer has big size? Give reason
16 38437Why 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.
1 7825how would you come to know if a transformer is double wound or auto? note that there is no tag. you are given only a multimeter.
