The Journey of TARIL: A Trusted Name in High-Voltage Transformer Manufacturing

The reliability of a national power grid is only as strong as its most critical nodes: the transformers. As India pursues an aggressive energy transition and global markets like the USA and Australia face aging infrastructure, the demand for high-performance transformer solutions is surging. In this context, experienced transformer manufacturers play a vital role in grid stability and industrial operations.

Transformers & Rectifiers (India) Limited (TARIL) occupies a strategic position in this landscape. In an industry where a single failure can lead to millions in lost revenue and grid instability, TARIL’s equipment serves as the backbone of modern electrical infrastructure.

Founded in 1981 and headquartered in Ahmedabad, Gujarat, TARIL is one of the most prominent transformer manufacturing companies in the world.

Transformers and Rectifiers India Ltd. is an India-based manufacturer of transformers and reactors, listed on Indian stock exchanges. With decades of operating experience, TARIL has established itself as a dependable power transformer manufacturer for high-voltage and high-capacity applications across multiple sectors.

With over 18,000 global installations and a presence in 40+ countries, TARIL has a reputation for handling complex engineering challenges. The company focuses on the design, manufacture, testing, and supply of power and specialty transformers for domestic and international customers.

The trajectory of TARIL is defined by a consistent climb up the voltage ladder. Since 1981, TARIL has been building transformers under the leadership of founder Mr. Jitendra U. Mamtora. What started as a transformer repair business quickly evolved into full-scale manufacturing of 33 kV to 66 kV units. The game changed in the mid-1990s when TARIL opened its Changodar plant. This facility enabled us to manufacture larger 110 kV transformers and eventually 245 kV class equipment. Today, we are a recognized name in India's power sector. The 2007 public listing on NSE/BSE marked financial growth, with milestones like executing 315 MVA, 400 kV units, and a 1200 kV class transformer for PGCIL's pilot project.

From 2011 onward, partnerships with ZTR Ukraine for 765 kV technology and licensing from Fuji Electric for shunt reactors helped TARIL enter the ultra-high voltage segment. Recent achievements include delivering India's first 1200 kV transformer to PGCIL and manufacturing eco-friendly transformers using natural ester oil. These milestones have driven record revenues and established TARIL as a leading transformer manufacturer in India.

Manufacturing Infrastructure and Capabilities

TARIL has three main factories near Ahmedabad. Together, we can build over 75,000 MVA worth of transformers annually, making us one of the biggest names in the business.

• The Moraiya plant is the main facility with a capacity of 40,000+ MVA per year. It produces and tests transformers up to 1200 kV and 1000 MVA, with full in-house facilities from core and coil to final testing.
• The Odhav facility has around 2,000 MVA capacity and manufactures smaller transformers up to 66 kV and 10 MVA for distribution needs.
• The Changodar plant adds 35,000+ MVA of annual capacity and focuses on transformers up to 200 MVA and 220 kV. This facility handles high-volume production using modern equipment and quality-controlled processes.

Combined, these three plants give TARIL a total manufacturing capacity of 75,000+ MVA per year, making us one of the largest transformer manufacturers in India.

TARIL manufactures a wide range of transformers and reactors customised for different applications and operating environments.

The product lineup is categorized by application and technical complexity:

• Power Transformers: These are built for massive power grids to transfer electricity over long distances. Units’ up to 1200 kV with ratings up to 1000 MVA. They are designed for utilities, grid inter-connections, and industrial power systems, with high reliability and low losses.

• Furnace Transformers: TARIL is the leading manufacturer, making units that can handle the extreme heat and power needs of steel plants and smelters. They support arc, submerged arc, ladle refining, induction furnace, and similar high-current applications.

• Rectifier Transformers: These units convert AC power to DC power. They are essential for industries that need steady, high-current DC flow. They are used in electrochemical processes, metal smelting, and industrial DC applications.

• Reactors: Reactors help stabilize power lines and manage "reactive power" to keep the grid steady. Both shunt and series reactors are produced to manage reactive power and stabilize long-distance transmission lines.

• Special Transformers: Custom-engineered transformers, including converter duty units for motor drives. They include converter-duty units, earthing transformers, and testing transformers customised for precise loads and performance needs beyond standard transformer ranges.

• Distribution Transformers: As established distribution transformer manufacturers, they offer high-efficiency units. They are designed for residential, commercial, and industrial electrification with low losses and robustness.

For engineering professionals, a transformer is only as good as its performance under fault conditions. Transformer designs are developed with a clear focus on electrical performance, thermal stability, and long-term reliability under grid and industrial operating conditions. Testing follows Indian and international standards, with type and routine tests on insulation, voltage withstand, ratios, and losses to ensure quality before shipment.

This strong engineering and testing capability is why utilities, EPCs, and industrial customers trust TARIL as a dependable transformer manufacturing company, not just a supplier.

TARIL’s impact extends far beyond the sub-station. With more than 18,000 transformers installed in over 40 countries, TARIL’s impact spans diverse applications globally, from national grids to specialized industrial environments.
