ECOsine Active Increased Grid Quality for Water Treatment facilities
- Utilities
Central wastewater treatment facilities need to meet stringent requirements in order to operate reliably and in an environmentally compliant manner. The responsible persons have. in particular, to ensure the availability of the plant on a 24/7 schedule. Numerous variable speed drives fro pumps and fans generate a harmonic content of the current in the supply that can lead to thermal overlkad of the electrical infrastructure and to malfunctions of sensitive equipment. In this application example, the power factor correction equipment suffered from significant additional losses caused by the harmonics.
The installation of ECOsine Active with a compensation current of 300A brought the required electrical and thermal relief to the PFC. The considerably improved power quality even made possible the installation of a back-up generator in case of a blackout, previously impossible because of the prevailing harmonic content.
