Operators of machines and plants are very demanding with regard to the quality of voltage supply:
- high supply security
- low investment costs
- effective energy use (low losses)
- low maintenance costs
- qualitative mains short-circuit power
In modern energy supply networks, voltage dips respectively fluctuations cannot be avoided. Voltage range deviations even increase in number and are often underestimated as a risk to industrial production processes. Failures of a duration of 20 ms can already result in considerable production problems. Instable supply voltage endangers the operational reliability, as short voltage dips of only tenth of a second have a negative impact on e. g. control devices, and thus may cause malfunctions or production interruptions.
Additionally, over- and under-voltages may lead to unwanted performance fluctuations of plants – with possible sincere disadvantages for the product quality or durability of plants.
Ruhstrat voltage stabilization systems secure this quality and protect against over- and under-voltage up to ± 50 %. Voltage deviations are corrected in real time and the mains voltage is continuously kept on the desired value. Reaction time to deviations of the nominal voltage is 140 μs, and the voltage is restored within ≤ 5 ms (regulation time) to the desired value.
