Transformer and watt or VA relation?

[neduet]

Hi friends
it is not ( problem or numerical) just i want know


friends if i have 15kva transformer .
then can i say it can carry 1500 watt 10 (split AIR conditioners) as a load.
and what happened if i add 5 more (split AIR conditioners) in same case. just give me idea please.theoretically


Additional Details
15kva transformer is step-down give 220 volt r.m.s output and
AIR conditioners (a.c)(with common power factor) also can operate on 220 volt or 1500 watt each.

No! Because:

Str should be greater than Pl/PF

However:
Str = 15 KVA
Pl = 10 X 1.5 = 15 KW
PF <1

I would say you can because the odds of all 10 being on at the same time are low. That's called "diversity".

M.S.J.'s point, though, was that the difference between kva and kw is power factor. Because of power factor, a reactive load draws a higher kva than kw.
