Hitachi Energy India has delivered a pioneering 400 kV, 315 MVA three-phase transformer filled with synthetic ester fluid to Power Grid Corporation of India Ltd (PGCIL). Manufactured at the Maneja, Vadodara facility, it represents the first transformer of this voltage class and capacity in India using synthetic ester insulation.
Synthetic ester fluid serves as a safer and more environmentally friendly alternative to conventional mineral oil. With a flash point over 300 degrees C and full biodegradability, it significantly reduces fire and environmental risks compared to traditional mineral oil solutions—offering improved safety, especially in densely populated or sensitive installations.
According to Venu Nuguri, Managing Director and CEO of Hitachi Energy India, the technology enables electrification while reducing operational risks in sectors such as utilities, energy-intensive industries, data centers, and renewable energy. He added that the collaboration with PGCIL reflects the company’s commitment to eco-friendly solutions aimed at reducing environmental impact and increasing energy efficiency.
