Answer Posted / blake
The KVA rating of a transformer takes into account the
power factor of the supply system. i.e. If you have a 100kW
load on your system with a supply power factor of 0.8 then
your transformer will need to be at least 125kVA. p.f =
KW/KVA. So to answer the question a KVA rating allows for
the fact that differnt installations can have different
power factors.
