Types of Transformers Manufactured in India

With rising excess power consumption and production, Indian manufacturers now offer a diverse range of equipment to facilitate the rapid electrification of the country. 

• Power Transformers: These are high-capacity transformers used in power generationand transmission stations. They are designed to operate at high voltages (765 kV) and are used to step up power for transmission over long distances. Organisations such as BHEL and TRIL are working to maximise efficiency in this area to prevent power losses in the national grid.
• Distribution Transformers: Also known as service transformers in residential areas, these handle the last mile of power distribution. They reduce the voltage to levels safe for both commercial and residential use, 230V or 440V. Unlike power units, these are designed to be efficient all day long, as they are subject to fluctuating consumer demand.
• Extra High Voltage (EHV) Transformers: EHV transformers are regarded as the backbone of the transmission system. These transformers can handle extreme loads, which at times reach up to 765 kV. These are required for connecting large renewable energy parks to the grid. This niche industry is a significant indicator of India’s engineering self-reliance.
• Speciality Transformers: This segment comprises customised solutions for particular sectors. Examples include Inverter Duty Transformers for solar power stations, Furnace Transformers for steel installations, and Dry-Type Transformers, which are fire-safe and oil-free, suitable for use in skyscrapers and metro stations.

How to Choose the Right Transformer Company?

When choosing a transformer manufacturer, the evaluation should go far beyond the quoted price. Here are some essential parameters to consider:

• Voltage Range: Confirm that the manufacturer has experience with your required voltage class.
• Customisation: Ensure they can tailor designs to meet specific site or environmental conditions.
• Certifications: Look for valid BIS, IEC, and ISO certifications that demonstrate quality and compliance.
• Testing Facilities: Prefer companies with in-house NABL-accredited labs for comprehensive testing.
• Delivery Capability: Review their track record for delivering large orders on schedule.
