Mechanical Dynamics & Analysis, Ltd. – St. Louis, MO

Work was recently completed on the first High-Speed Balance Facility in the St. Louis area, for power generating equipment, at Mechanical Dynamics & Analysis (MD&A). The facility was designed to be the one of the most modern balance facilities for power turbines in the United States with the ability to balance both steam and gas turbines as well as generator fields.  The project team was lead by Tarlton Corporation and included critical team members Corrigan Company for the mechanical work and Schaeffer Electric Company for the electrical work.  Key portions of work for Schaeffer included variable frequency drives and power for 8000 hp and 3000 hp motors, building addition, new Ameren 14 MVA substation, 15KV customer switchgear, (5) 15KV transformers, cooling tower, (3) UPS systems, extensive process control, vacuum penetrations, along with general lighting and power.  Schaeffer could not be more pleased with the team atmosphere throughout this project promoted by Tarlton and MD&A.  It took a strong collective effort to complete the project in the timeline required and it was exciting to be a part of that effort.

Saint Louis University Hospital – Nurse Call Upgrade

Schaeffer Electric’s Data & Communication division recently completed a Nurse Call upgrade at St. Louis University Hospital.  This complicated renovation required our electricians to maintain the two existing nurse call systems while installing and integrating the new Hill-Rom system with approximately 1,400 devices. In addition, the new system required a new dedicated fiber optic network to be installed.  The project was completed successfully, on time and on budget.

Metro Link – Light Rail Expansion Fiber Network

Schaeffer Electric performed all the low voltage work along seven miles of new track with ten new stations.  Work in the stations included electrical work supporting the low voltage systems. Wiring and device hookups were performed for the following systems: SCADA, voice, data, fire alarm, CCTV, radio antennas, and ticketing just to name a few. All the fiber optic cables were brought into each station spliced and connectorized. Active fiber splice cases were accessed with the new stations being spliced in on two hour time frames.
