What is the difference between power transformers and distribution transformers ? Ans.Those transformers installed at the sending or receiving end of long high-voltage transmission lines are the power transformers. The distribution transformer (generally pole mounted) are those installed in the localities of the city to provide utilization voltage at the consumer termi nals. (i) Power transformers generally operate at nearly full-load. However, distribution transformers operate at light loads during major part of the day. (ii) The performance of a power transformer is generally judged from commercial efficiency whereas the performance of a distribution transformer is judged from all-day efficiency (iii)The rating of a power transformer is many times greater than that of a distribution transformer
