Our engineers manufacture auto transformers that are widely used in various power applications. These transformers interconnect the systems operating at varied voltage classes. They are often used to provide conversions between the two common domestic mains voltage bands e.g. (100-130 and 200-250).
The auto transformers are used on long rural power distribution lines. In such cases, auto transformers that are equipped with automatic tap-changing equipment are inserted as voltage regulators. This is done so that the customers at the far end of the source are able to receive the same voltage as those closer to the source.- A. B. C. Transformers Private Limited
auto-transformer is a continuously variable voltage transformer, having a single layer winding on a toroidal core of high grade Cold Rolled Grain Oriented Steel. On one face of the copped winding, along the periphery, a special durable contact surface is made. A specially designed carbon brush slides smoothly on the surface. A contact arm holding the contact brush is fitted to the central shaft and as the control knob is rotated, the carbon brush slides over the winding and taps off a portion of voltage across the winding. Any desired voltage within the maximum range can be obtained by adjusting the position of the brush. The calibrated dial reads approximately the output voltage at no-load, when the input is at its rated value. Rotation of the brush arm by manual of motor drive delivers an output voltage from zero to or above line voltage. Variacs fitted with voltmeter, ammeter, fuse, switch, pilot lamp etc. can be made in Enclosed type models with extra cost. For the more...

- Powerline System
Rec9hs 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 more...
