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.

H.T. Automatic Voltage Stabilizers are used to get stable input voltage for individual Distribution Transformer, irrespective of High / Low Voltage being received from Electricity Authority. These are installed on the input side of the Transformers. It also prevents the Transformer from getting overloaded.

RECON’S H.T. Automatic Voltage Stabilizer takes care of wide voltage variation ranges, sleeplessly and in ON LOAD condition, leading to full load utilization of the Transformer, installed.

RECON’S H.T. Stabilizer Comprises of:

1. Step down unit double wound.

2. Buck Boost Unit double wound.

3. Stabilizer unit auto wound delta connected with rolling contacts capable of moving on
    the winding through Automatic / Motorized / Manual mechanism for regulation of the
    voltage at the output side.

4. Control Unit.

Built as per Customer’s Specifications.
