Answer Posted / ashokreddyreguri
flux is proportional to E\f or V\f
if the frequency is reduced the ratio V\f will increase so
flux will increase.so to maintain this flux magnetizing
current required will increase.this reduces the no load
power factor , so on load power factor is also reduced.
this also reduces o\p of transformer.so V/f ratio of t/f
must be maintained constant.
as 50% of frequency is applied to maintain constant V/f
input voltage applied must be 50%if rated voltage
