Difference in Frequencies?
Your
AC Transformers FAQ
Difference in Frequencies? This is an
important aspect of AC transformers
to
understand because voltage greatly impacts transformer design and usage.
Basically, AC transformers designed for 50/60Hz operation can be
utilized at frequencies up to 400 Hz. Transformers designed for 60 Hz
can also be used at frequencies up to 400 Hz but cannot be used at 50
Hz. With AC transformers 50Hz to
400Hz at 24V to 480V are quite common. This just begins to scratch
the surface of Difference in Frequencies.
With Difference
in Frequencies, it is important to note that the transformer cannot
change the frequency of the supply.
For instance, if the
supply is 50Hz, the output will also be 50Hz. In Europe, 50Hz is
commonplace but in America, 60Hz is the norm. The 50Hz frequency
typically utilizes 230V RMS while 60Hz generally utilizes 117 V RMS.
Devices and
appliances should be utilized on either 50Hz or 60Hz as recommended by
their specific manufacturer. Operational safety cannot be ensured
otherwise.
Another
area of importance with
Difference in Frequencies is the effect
of varying frequencies. For instance, if the transformers frequency is
increased,
the inductive reactance of the windings is also increased. This causes
a
greater
AC voltage drop across the windings with a lesser AC voltage drop across
the
load. It should be noted that this increase in frequencies, generally,
should not damage the transformers. However, with a decrease in
frequency, the reactance of the windings is decreased while the current
through the windings is increased. The decrease in frequency coupled
with the increase in current, generally, results in damage to the
transformer. In conclusion, with Difference in Frequencies, a
transformer may be operated at frequencies above its normal frequency,
however, damage is a strong probability if it is operated below its
normal frequency.
