L.T. Automatic
Voltage Stabilizers |
| RECON’S Automatic Voltage Stabilizers
are Auto Wound Transformers having helical coils mounted
on a conventional laminated core. Carbon Rollers assembled
on a fiber glass carrier board traverse the length of the
Coil Track. These rollers are electrically connected to
the output terminals and as they are driven over the track,
a variable voltage is obtained.
Beneath the regulating coil a number of compensating winding
are connected in parallel and short circuited to reduce
the effect of core-flux ‘fringing’ and keeps
the reactance of the regulator fairly constant at any position
of the rolling contact.
The variations of more than ± 1% of the rated output
voltage of the stabilizers are sensed through solid state
relay which sends signals to the controlling servo motor
which further drives the roller mechanism in such a direction
so as to increase or decrease the voltage and stabilize
it to the rated output voltage. Solid State Relay operates
on 230 V, 1Ø supply.
L.T. Automatic Voltage Stabilizers holds its potential for
units having either L.T. Supply or Low capacity H.T. Connections.
The same can be manufactured for Balanced Supply and Unbalanced
Loads or Unbalanced Supply and Unbalanced Loads.
The range of input supply which the stabilizer is designed
for depends upon the voltage condition at the supply point.
However some standard ranges for L.T. Stabilizers are as

ADVANTAGES:
- Prolonged coil life (15-20 years) under normal working
conditions, due to robust
winding.
- The graphite rollers roll, while sliding on the coil track,
so contact point of the roller
goes on changing which prolongs the life of the rollers.
- Without lifting the complete assembly, the rollers can
be inspected / replaced by
opening the top cover only.
- Can be manufactured for both indoor and outdoor installation.
