Answer Posted / shahulsnfa
See, KVA is apparent power which means the power
available. and KW is real power which means how much power
utilised from available power.
motors are utility machines which consumes the power
from the source for its working. and the generator are
producers and not consumers. the motor consumes the power
in terms of voltage and current.
when phase angle difference btwn current and voltage
is zero, then KW=KVA. but the phase angle difference
between current and voltage will have some value regarding
load. so the real power is determined by the load and not
by the source.
that is why macines are rated in KW and generators are
in KVA. and the transformers are transforming power rather
than consuming.. so they also rated in KVA.

how does ELR works? explain
at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
