Answer Posted / aamod tripathi
Frequency has a role when the load is either inductive or
capacitive. The inductive reactance or the impedance
offered by inductor increases with increase in frequency
and In case of capacitive reactance the impedance offered
by capacitor decreases with frequency increase.
If the frequency applied to the instrument is more than the
specified frequency the losses increase and can give
devastating results in inductive loads.
for resistive loads frequency has no meaning.
for measuring instruments. the construction of the
measuring instrument needs to be checked if PMMC or MI or
induction type.... it will increase the oscillations or
will give incorrect reading. It shall be noted this is why
each and every electrical instrument/ Machine/ Grid has a
frequency range.
