Missouri American Water, Knob Hill Switchgear Replacement
St. Louis, Missouri
One of the two outdoor 4kV switchgear lineups for Missouri’s largest water treatment plant was replaced in phased stages to maintain plant operations. New vacuum, draw-out, circuit breaker switchgear was designed in a weather-proof enclosure with remote control via SACAD interconnect. Design for future emergency generator connection is provided. A short circuit/coordination study provided proper short circuit ratings and relay settings.
