HT AVR (High Tension Automatic Regulator) Upto 5000 KVA
Servokon offers precision engineered state-of-art HT Servo Stabilizer (HT AVR), as the name suggests this AVR operates "on load", continually and directly on the HT line giving stabilized HT voltage output. The fluctuating HT voltage from grid supply is initially controlled by the HT AVR with accuracy of +/-1% and then fed to the transformer resulting in constant LT output within +/-1% accuracy. This can be understood better by the schematic diagram shown below:

Transformer with Built-in AVR
Servokon offers precision innovative state-of-art Transformer with built-in AVR, which is combination of HT AVR and a standard distribution transformer. The fluctuating HT voltage from Grid supply is initially controlled by the HT AVR with accuracy of +/-1% and then fed to the transformer which transforms in into its standard ratio to LT voltage. Subsequently, stabilized HT voltage will result in stabilized LT voltage with an accuracy of +/-1%. Basically input will be 11/33kv and the output will be LT voltage with +/-1% can be obtained through a single product. This can be understood better through the following schematic diagram given below:
