Answer Posted / ik3232
If the frequency applied to a transformer is increased, the
inductive reactance of the windings is increased, causing a
greater ac voltage drop across the windings and a lesser
voltage drop across the load. However, an increase in the
frequency applied to a transformer should not damage .
But, the applied frequency of the transformer is less than
the normal Frequency, the reactance of the windings is
decreased and the current through the transformer winding is
increased. If the decreasing frequency is enough, the
resulting increasing current will damage the transformer.
For this reason a transformer may be used at frequencies
above its normal operating frequency, but not below that
frequency.
