Ltd Low Power Quality - Symptoms Measurement errors in metering equipments Spurious operation of fuses, circuit-breakers and other protective devices Voltage glitches in computers systems resulting in lost data Electromagnetic interference with TV, radio, communication & telephone Malfunctioning of standby generators and associated AVR control equipments Excessive temperature rise in motors, transformers Failure of Power Factor correction equipments Malfunctioning of precision equipments © P2Power Solutions Pvt. Ltd Case Study – Client Details Sector - Newspaper Printing DG Rating - 380kVA Peak Demand - 330A Load Profile - 2x135kW DC drives 15kW Compressor Lighting Loads iTHD - 28% PF - 0.76 © P2Power Solutions Pvt. Ltd Case Study – Client Details The backup Diesel Generator started hunting whenever the load current demand went beyond 200A. The client wasn’t able to carry out production in full capacity using the backup generator P2 Power Solutions audited the site and found the current harmonic distortions to be significantly higher than recommended limits The power factor was also low due to which the peak apparent current demand on the DG was high We recommended the installation of a P2 Power Active filter for harmonic mitigation and power factor correction © P2Power Solutions Pvt.
