Explain working of servo controlled voltage stabilizer.
Answer Posted / thowsif_emerson
This is a stabilizer. which constantly monitors the output
voltage and controls the variations in the input voltage
by movements of a motor. This motor in turn selects the
proper output voltage on the variable transformer (variac).
This is probably the cheapest power-conditioning product
available. It gives reasonably good voltage regulation and
is all right where voltage fluctuations are not
considerable. However it is not advisable to use it outside
big cities where apart from considerable fluctuations in
voltage, the power is full of frequency drifts, failures,
noise and spikes.
