Eco-efficient and Innovative A sustainable range of green eco-efficient power transformers, from 10 to 500 MVA and up to 550 kV. GE creates and delivers customer-valued network solutions for an energy-efficient future. Our environmentally-friendly solutions are aimed at meeting major energy challenges of today and tomorrow: energy efficiency, market efficiency, grid reliability and environmental concerns. GE Green Power Transformers offer significant environmental benefits, including better product performance, covering the 3 phases of the product life cycle: • Manufacturing: reduced consumption of natural resources • Operation: lower CO2 emissions, limitation of environmental-risk, noise reduction. space savings and energy efficiency • End of life: recyling capabilities of products Eco-efficient Power Transformers Based on customer demand for environmentally friendly products that improve life cycle costs with limited maintenance needs and increased service lifetime, GE introduces its Green Power Transformers to accompany and assist customers with today’s ecomanagement challenges. A Green Power Transformer (10 to 500 MVA and up to 550 kV) is a sustainable, eco-efficient product with the following functionalities: • Filled with natural ester instead of mineral oil • Hermetically-sealed tank design, equipped with patented expandable radiators and OLTC with vacuum type tap changer • Innovative technologies to reduce acoustic energy transferred and optimized design of the active part • Optimized low loss levels • Solvent-free paint Complementary Offering • On-line MS3000 monitoring system • Resin Impregnated Paper (RIP) bushings with composite insulators • Cooling unit with speed-controllable EC fans Customer Benefits • Optimized low loss levels • Prevention of pollution and increased safety by using natural ester insulation liquid • Innovative technologies to reduce noise level • Reduced maintenance cost, extended life time and increased overload with hermetically-sealed tank design, equipped with patented expandable radiators and vacuum type tap changer • On-line condition monitoring system MS3000 • State-of-the-art factories around the world

Green Power Transformers A sustainable range of green eco-efficient power transformers from 10 to 500 MVA and up to 550 kV Key Customer Benefits Green Power Transformers offer a new alternative for customers who want to preserve the environment by offering a lower carbon footprint, limited pollution risk and optimized life cycle costs thanks to less maintenance. Other advantages include reduced ageing, lower noise levels and increased fire safety. To further maximise operational management and prevent faults and damages, advanced on-line monitoring systems can also be added. Environmental and...

Green Power Transformers High eco-efficiency A major benefit of the Green Power Transformer range is its optimized life cycle cost. In our standardised process, design choice and high-performance materials achieve low losses for the optimal capitalised cost of the transformer. GE’s innovative hermetically sealed tank design, equipped with patented expandable radiators, goes a step further in reducing life cycle costs: it reduces maintenance, extends life time by preventing contact between the oil and moisture, and oxygen in the atmosphere. Hermetically sealed tank design reduces cellulosic insulation...

Key references Bringing the bulk of energy closer to consumption centres and investigating green solutions EDF Energy installed the first purpose-built 132/33 kV 90 MVA 3phase Green Power Transformer filled with ester in the United Kingdom. Located in Luton’s interconnection substation, it is equipped with our MS monitoring system to ensure the highest availability possible during operation. This power transformer is installed close to consumption centers, and the liquid is made from edible soya beans, which are fully biodegradable and have greater fire resistant properties. Lowering maintenance...
