Working of HT 2 in 1 Combo?

The main work of the H.T. Automatic Voltage Stabilizer is to control the fluctuation to manage the load on the electricity. And provides the constant L.T. Output within ± 1% accuracy. Electricity input is initially stabilized by the Built-In H.T. Automatic Voltage Stabilizer.

As the normal distribution transformer generally manage the voltage to high tension to low tension. And due to this the fluctuation problems occurs which leads to various accidents and serious problems. The electrical items have been damaged and creates improper function of electrical systems.

H.T. Transformer gives us the total solutions. Because of the quality of our products our product manages all the problems. And provides the proper solution to remove the problem of fluctuation.

We are the largest manufacturers of H.T. Automatic Voltage Stabilizer in India. We stabilized our name over the seven seas. Due to the quality and the durability of our product we are best from any other brand. It is available up to 10,000 KVA in 11 KV & 33 KV Class.

Why we need HT AVR?

Basically, Distribution transformer Steps-Down the voltage from H.T. to L.T. However, it cannot take care of the fluctuating voltage and most of the time and at most of the sites.

It has been understood that the issue of fluctuating voltage remains, resulting in unsuitable function of electrical systems. H.T. Transformer with Built-In H.T. Automatic Voltage Regulator provides total solutions for voltage fluctuation and stabilization.

The unit is basically a combination of H.T. Automatic Voltage Stabilizer and standard H.T. Distribution Transformer working in conjunction. These are available up to 10,000 KVA in 11 KV and 33 KV Class.

Standard transformers can accurate limited voltage variations and can’t regulate the voltage in ‘on load’ condition. The only smart way to tackle this problem is by installing a highly efficient Balaji Power Automation H.T. Transformer with Built-In H.T. Automatic Voltage Stabilizer.

These systems can be used in various industrial as well as commercial applications.

Advantage of H.T. 2 in Combo

  • Due to its compact size, it saves space.
  • The installation cost of the H.T. Automatic Voltage Stabilizer is very low.
  • H.T. Automatic Voltage Stabilizer has better efficiency.
  • By the use of H.T. Automatic Voltage Stabilizer, there is a reduction in the electricity bill.
  • After the installation of the HT 2 in 1 combo the transformer losses have reduced.
  • There is a benefit to installing the H.T. Automatic Voltage Stabilizer because due to this the current in the L.T. AVR is very high


HT 2 in1 Combo or Transformers with Built-in HT-AVR are effectively required at all such places. Where controlled and constant voltage is one of the most important requirements.

And are suitable where breakdown due to voltage fluctuation results in heavy financial losses such as Hospitals, Laboratories, Various Life Saving & Testing Equipment. Pharmaceuticals, Research Institutes, Defense, Telecommunications, Air Conditioning, Data Processing, Electronics based Industries, Educational Institutes and Food Processing Units.

Paper plants, Footwear and Leather Industries, Cement Plants, Textile Industries, Moulding Units, Hotels, Farm Houses, Offices and Residences Housing Apartments, and so on.
