Power transformers

The efficiency of a power transformer plays a critical role in determining overall energy consumption in electrical systems. A highly efficient transformer minimizes energy losses during the transmission and distribution of electricity, which directly reduces the amount of power wasted as heat. This not only lowers operational costs but also contributes to a more sustainable energy infrastructure.

When a transformer operates at high efficiency—typically above 95%—it ensures that more of the input electrical energy is delivered to the output without unnecessary loss. In contrast, low-efficiency transformers can lead to significant energy waste, increased carbon emissions, and higher electricity bills.

Improving transformer efficiency is especially important in large-scale power grids and industrial applications, where even small percentage gains can translate into substantial energy savings. Additionally, energy-efficient transformers support compliance with environmental regulations and help organizations meet their sustainability goals.

Siemens Energy is driving sustainability in the transformer industry by decarbonizing its supply chain, optimizing raw material use, and greening its manufacturing operations. Through initiatives like the Supply Chain Decarbonization Program, the company collaborates with partners to reduceemissions from critical materials such as steel, copper, and aluminum. Siemens Energy has pioneered transformers made from 100% recycled copper and is advancing green steel and aluminum solutions By enhancing transparency with material passports and life cycle assessments, Siemens Energy empowers customers to make sustainable choices. These efforts set a benchmark for the industry, supporting the transition to a greener, more sustainable energy grid.

Siemens Energy power transformers enable the seamless integration of renewable energy sources into the grid by ensuring efficient energy transmission and grid stability. With advanced DC compensation technology, they mitigate DC components from HVDC systems, ensuring reliable operation and protecting the grid from disruptions. Designed for flexibility and high efficiency, these transformers handle variable renewable inputs while minimizing energy losses, making them ideal for sustainable energy systems. Siemens Energy’s innovative solutions support the transition to a greener, more resilient energy future.

Siemens Energy’s mobile resilience units provide a fast, flexible, and sustainable solution to ensure power continuity during emergencies or planned maintenance. As part of the innovative PRETACT® program, these units are designed to keep critical operations running while minimizing downtime and maintaining grid stability.   

Unlike traditional transformers that can take months to replace, Siemens Energy’s mobile units can be delivered and installed within weeks, enabling rapid deployment and immediate power restoration during outages or emergencies. Their modular, multi-voltage design allows seamless integration into various grid configurations without the need for extensive system redesigns.   

Equipped with Sensformer™ technology, these units offer real-time cloud-based data monitoring, allowing operators to optimize performance and detect potential issues proactively. Additionally, their use of biodegradable insulating fluids, such as ester liquids, enhances safety, improves thermal performance, and reduces environmental impact.   

Whether responding to transformer failures, natural disasters, or routine grid upgrades, Siemens Energy’s mobile resilience units act as a reliable safety net for the power grid. By combining advanced technology, rapid deployment capabilities, and sustainable materials, they ensure uninterrupted electricity supply and set a new standard for grid reliability.
