INDUCTION REGULATOR TRANSFORMER

Induction regulator
The induction regulator is similar in design to a
wound-rotor induction motor but it is essentially a
transformer whose output voltage is varied by rotating its secondary relative
to the primary—i.e., rotating the angular position of the rotor. It can be seen
as a power transformer exploiting rotating magnetic fields. The major advantage of the
induction regulator is that unlike variacs, they are practical for transformers
over 5 kVA. Hence, such regulators find widespread use in high-voltage
laboratories.
