EEE :: Transformers
- The efficiencies of transformers compared with that of electric motors of the same power are
- The noise resulting from vibrations of laminations set by magnetic forces, is termed as
- The power transformer is a constant
- Sumpner's test is conducted on transformers to determine
- For the parallel operation of single phase transformers it is necessary that they should have
- In a transformer routine efficiency depends upon
- No-load on a transformer is carried out to determine
- Losses which occur in rotating electric machines and do not occur in trans formers are
