in power station power measuring unit is KW but in
transformer is KVA why?
Answer Posted / dipak patil
the tf cu losses are proportion to current and irone or no-
load losses are propotional to voltage rating of
transformer. Since losses once available it is essy to
calculate transformer efficiency. Hence tf rating is given
in KVA insted of KW
