Siemens has successfully tested three mobile resilience generator-step-up units (GSU) for a U.S. wholesale energy provider Southern Power.

The three versatile mobile transformer units manufactured as part of the Siemens Pretact concept are expected to increase power security at generating stations.

These GSUs are designed as single-phase units with a transport weight of just 49.8 tons each, making them highly lightweight by using high temperature insulation material.

The units are also versatile in voltage and they can operate in multiple configurations, either at 230 kV or 115 kV and a low voltage of 34.5 kV.

The manufacturer says this 150 MVA bank of transformers can be installed in approximately 24 working hours.
