Missouri American Water, North Plant Main Switchgear & Motor Control Replacement
St. Louis, Missouri
The existing indoor 4kV service entrance was replaced with new vacuum circuit breaker switchgear. Provisions were made to connect and control future 4kV, 2000kW generators throughout to the new switchgear. Aging high-service pump motors and controls were replaced with new solid-state synchronous controllers, vacuum contactors, and medium-voltage variable frequency drives. These were interfaced with the existing plant SCADA system. Pre-purchase, bidding, and construction phase services were included.
