© P2Power Solutions Pvt. Ltd Case Study – Client Details The backup Diesel Generator started hunting whenever the load current demand went beyond 200A. The client wasnt 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
