Explain why machinery used on a.c supply is usually rated
in KVA instead of KW?

Answer Posted / mani2089

kw = kva * power factor
The power factor affects the maximum demand component of
the network charges. Generally, kva demand tariffs are
structured to be revenue neutral compared with kw demand
tariffs at a power factor of 0.8
