Hitachi Energy has dispatched India’s first 400 kV class three-phase power transformer using synthetic ester fluid to Power Grid Corporation of India. This development marks a major step forward in environmentally sustainable and high-performance power infrastructure, according to a company release.
Designed for enhanced efficiency and safety, these transformers can operate at higher temperatures and handle larger load capacities. This results in lower operational costs, improved energy efficiency, and reduced fire risks due to the ester fluid’s high flash point of 330°C. The synthetic ester fluid, being biodegradable, also minimizes environmental impact, making it ideal for use in sensitive and densely populated locations.
The transformer, rated at 315 MVA, is the largest of its kind in India both in voltage and capacity. Built entirely in Hitachi Energy’s Maneja facility in Vadodara using its Trafostar global platform, the equipment represents progress toward India’s self-reliance goals in the power sector.
Hitachi Energy, headquartered in Switzerland, is a global leader in power grid solutions, supporting sustainable electrification through advanced technologies in transformers, high-voltage equipment, and grid automation. With operations in over 140 countries, the company serves sectors such as utilities, industry, transportation, data centers, and infrastructure. In India, Hitachi Energy operates under Hitachi Energy India Limited, listed on NSE and BSE as POWERINDIA.
As part of the larger Hitachi Group, the company integrates IT, operational technologies, and physical products to address energy and infrastructure challenges worldwide. Hitachi’s global operations span energy, mobility, digital systems, and connected industries, with FY2024 revenues reaching nearly 9,783 billion yen and a workforce of approximately 280,000 employees globally.
