Not only generator but UPS / Transformer or any other
device which is giving Electrical power as output is rated
in kVA. The reason is that it is power that will be given
by the machine apperently. however when the load is
connected say for example a motor the actual power which is
converted to work is diffenrent known as active power and
involves power factor. There fore all machines with
mechnical output are rated in kw.
