for Nuclear Power Plants

Inverters Single- and Three-Phase Systems

Due to the very stringent safety requirements for equipment installed in Nuclear Power Plants (NPP) and the long operating periods of such plants, the BENNING inverter systems for NPP applications have been designed for a life time of more than 40 years. The inverter systems have also been designed and qualified to fulfill seismic and other NPP requirements and are manufactured and tested according to the quality procedures required for 1-E NPP applications.
