Southern States TranSwitcher®

/

The Southern States TranSwitcher® is a renewable intertie solution designed specifically for switching and protection of power transformers. Its unique design makes it ideally suited for distribution systems that intertie with solar farms as well as other distributed energy resources. The use of a “soft close” helps to minimize system voltage drops and potential ferro-resonance issues caused by the high inrush currents associated with DER transformer energization. Employing the TranSwitcher® can help utilities increase the life of their transformer as well as maintain system power quality.
