Transformers Analysis CHANGGAO

Real transformers on the other hand are not 100% efficient and at full load, the efficiency of a transformer is between 94% to 96% which is quiet good. For a transformer operating with a constant voltage and frequency with a very high capacity, the efficiency may be as high as 98%. The efficiency, η of a transformer is given as: Transformer EfficiencyMissing:CHANGGAOMust include:CHANGGAO[PDF]Practical Transformer Handbook - Kishore Karuppaswamy
