HT Automatic Voltage Regulator
Our Integral Transformer with HT-AVR is a distribution transformer upto 3000 KVA capacity with an integral servo voltage regulator connected on the HT side of the transformer. Its superior features not only help you to conserve energy but also avoid detrImental effects of over voltage, under voltage and unbalanced voltage on your costly electrical equipment & finished products.
Constructionally, it consists of two
interconnected tanks, one housing the
distribution and buck-boost transformers and
the other housing the servo voltage controller
as shown in the single line diagram. In case
there is a voltage fluctuation on the HT side
the controller will move the carbon brushes on
the dimmer unit to tap the equivalent of
voltage to be added or subtracted on the HT
side. This voltage would then be fed to the
buck-boost transformer connected to the HT
input of the distribution transformer. The
buck-boost transformer will, in turn, add or
subtract it from incoming HT voltage, so that
HT voltage is always maintained at its set
value. A bypass handle is provided to ensure
that the voltage control unit can be bypassed,
in case needed.
The entire unit is designed as an outdoor, oil
cooled unit with a simple bypass system. This
will ensure that the transformer continues to
work uninterruptedly in the unlikely event of
a breakdown in the voltage regulator unit.
