Siemens has announced a power transformer technology portfolio engineered and adapted to address resiliency and power security challenges in the U.S. market, and help utilities respond to the new pressures to invest in protecting and updating their transformers to be able to react in cases of emergency.

LPTs are custom-designed and cost millions of dollars to replace. Due to their weight between 100 and 400 tons apiece, they are extremely difficult to transport. According to a 2012 Energy Department report, the replacement of LPTs could take 20 months or more due to the complex procurement rules for the technology and the fluctuating price of copper and electrical steel in recent years.
