Basic Circuit of H.T. AVC:

Global’s H.T. AVR primarily consist of the following:
A. Step Down Transformer
B. Voltage Regulator.
C. Buck/ Boost Transformer.

H.T. AVC (Servo Stabilizer)

H.T. Automatic Voltage Regulator (Stabilizer) to be installed on the incoming side of the Transformer and provides stabilize input voltage to the Distribution Transformers.

Advantages of Installing H.T. Automatic Voltage Controller:
1. H.T. AutomaticVoltage Stabilizer supplies rated Stabilized Voltage to the transformer, there by the utilization of the transformer will be up to full rated capacity and is protected from High/ Low Voltage Fluctuation.

2. Life of the Transformers are increased by installing Stabilizer on HTside.

3. Where Nos. of Distribution Transformer are installed in a plant, you can install only one H.T. Automatic Voltage Controller (Regulator).

4. losses of transformer will reduce after installation of HTAutomatic Voltage Controller.

5. Shorter Payback period.

6. In Higher Capacity, it is technically advisable to install H.T. Automatic Voltage Controller because current in L . T . Stabilizer is Very High.

Construction of H.T. AVC:

Global’s H.T. AVR primarily consist of the following:
A. Step Down Transformer
B. Linear, plus/ minus type vertical Voltage Regulator.
C. Buck/ Boost Transformer.
D. Electronic Control Circuit.
The item (A) & (C) will be housed inside a sheet tank fitted with cooling radiators and mounted on uni-directional rollers and item (B) will be housed in separate tank
