Answer / niladri

its mean the multiplication of secondary voltage & current
of transformer.

Answer / sudarshan

1250 kva is rating of transformer & it is apparent power
Apparent power=VA
TRANSFORMER TRANSFORM ENERGY WITHOUT CHANGING FREQ.
WE GET POWER IN SEC. SIDE CORRESPONDING WITH PRI. SIDE
KVA=√3VA
=1.73VA
