Application Challenge
The established system, an 18-pulse Benshaw model AC drive, powered four 350 HP wastewater lift pumps. Approximately 12-13 years into its operational life cycle, it began experiencing technical issues, particularly with its crucial power supply components.
The resolution required meeting two major objectives. Firstly, it was essential to retain the same physical size as the current Benshaw drives, which necessitated the reuse of the existing enclosures. Secondly, the drive's harmonic performance and efficiency needed to meet, if not surpass, the previous standards. Additionally, the utility aimed to minimize their motor drive systems' heat output to lower the ambient temperature of the MCC room and potentially enhance the vibration performance of the pumps.
