Siemens continues to advance power transformer technologies with a portfolio of solutions to prevent failures, protect assets and react in cases of emergency to address resiliency and power security challenges for the U.S. market. Siemens’ new mobile resiliency transformers allow utilities to react rapidly and replace units within days or energize within few hours rather than weeks in times of major substation events like extreme weather. Siemens’ bullet-resistant transformer protection systems, which can be installed on new or existing units, help protect the power grid against physical security threats. For installations near bodies of water or other ecologically sensitive areas, transformers filled with synthetic or natural ester oil offer an environmentally-safe, modern solution. And transformers specifically designed for geomagnetically-induced current (GIC) resistance can protect the power grid against solar storms that can result in widespread blackouts. These technologies help power providers both plan for and respond quickly in order to keep the power flowing for millions of customers across the country.

“Our portfolio of resilient, advanced transformer technologies has been designed and engineered to answer the unique challenges facing the U.S. market while also helping our customers plan for the future,” said Richard Boyd, vice president of Siemens Transformers in the U.S. “Transformers play an essential role in securing our power systems for the 21st century, meeting NERC and FERC regulatory standards for the grid, and most importantly, allowing utilities to protect and restore power for millions of energy consumers.” 

The mobile resiliency transformers are designed to be as flexible as possible to minimize local transportation and installation requirements. In addition, the transformer design includes pre-installed cooling systems with operation on multiple voltage levels. With this versatility, utilities can avoid investing in a spare unit for each transformer rating.  To minimize the size and weight of the transformers, high temperature insulation material and forced oil cooling equipment is used. Special plug-in bushings and connections reduce installation time to approximately one to three days, without transformer entry and oil handling, instead of weeks it may take to transport and install normal available spare units. In cases where utilities do not have existing spare units, it may take 6-12 months for new units to be procured, shipped and installed. 

Siemens has also developed new bullet-resistant transformer technology with special armor panels, similar to tank-mounted sound panels, installed externally to protect against physical threats to the power system.  This technology is designed and tested to withstand stringent ballistic requirements, as a solution for those high-risk installations.

For power providers that service environmentally sensitive areas, ester oil-filled transformers offer an alternative power source that is biodegradable and available in either natural or synthetic form. These transformers are also a viable solution for renewable energy generation sources, such as hydro-electric dams.

Additionally, Siemens offers geomagnetically-induced current (GIC) safe designs that can protect the power system from transformer failures caused by solar storms. Lloyds, a leading global insurance company, estimated that a large sun storm could cause permanent damage to transformers and result in blackouts of 16 days to years and affect over 20 million people. Siemens GIC-safe units can help utilities plan for and protect against these events.

Finally, a broad portfolio of preventive service measures offered by Siemens assists transformer operators in predicting potential failures and taking precautions to minimize operational risks. Monitoring, condition assessment, retrofitting and repair can enhance grid resiliency and advance transformer investment and technology into the future.
