Three Phase 2000KVA (2MVA) HT AVR-High Tension Transformer with Automatic Servo Stabilizer

HT-AVR or HT-Automatic Voltage Regulators are the high-tension stabilizers that protect electrical equipment from overloading of voltage. These voltage regulators supply a continuous and stable input voltage. Manufactured using hi-tech technology, the automatic voltage regulators are capable of managing load conditions and wide voltage fluctuating ranges. The solid state relays integrated in the voltage controllers sends signals to the controlling servo voltage stabilizer motor. Further, it drives the roller mechanism in a specific direction to bring the voltage equivalent to the rated output voltage.

Construction In High Tension-Automatic Voltage Regulators, there are helical coils mounted on a conventional laminated coreCarbon rollers goes around the length of the coil track & are assembled on a fiber glass carrier boardThe rollers are connected to the electric output terminalsParallel connection of compensating winding near the regulating coil is doneThe connection between the windings and regulating coils is short circuited so as to reduce the effect of core-flux fringingIt keeps the reactance of the regulator constant at any position of the rolling contact
Technical Specification Solid state relay can sense variations: ± 1% of the rated output voltageRelay operates on: 230 V, 1Ø supplyOutput Accuracy: +/- 1ïficiency: above 98%
Advantages Low replacement cost5% to 10% saving on energy consumptionReduction in breakdown period of the machines100% capacityOn Load step-less voltage variation
