When Mercedes-Benz USA International (MBUSI) began building a sophisticated plant to manufacture its M-Class sport utility vehicle, the company was determined to find an equally sophisticated system for monitoring and troubleshooting power quality problems, minimizing downtime, and reducing energy costs. The system they got from Square D paid for itself in two years ? one year ahead of schedule.

Market growth and frequent product innovations were forcing the facility personnel at Smith and Nephew's Memphis plant to struggle to keep up with the demand for changes in the manufacturing processes. Without a good monitoring system to provide an accurate picture of loading, electricians struggled to determine if particular circuits could handle new loads. After installing a PowerLogic system, the staff soon had accurate peak demand data that allowed them to add new loads to existing circuits and avoid a $2 million expansion.

Durham College needed more electrical data in order to manage energy saving projects. Following work completed by Square D POWERLOGIC, the the base load dropped from 600,000 kWh per month in 1989 to 400,000 kWh per month in 1997. The average demand peaks were also reduced from 1,600 kW to 1,000 kW over the same time period. As a result of these reductions the College realized a cost savings of approximately $400,000 in 1998.

A PowerLogic system installed to help keep an eye on costs helps uncover costly errors in the plants utility metering. After reviewing data from PowerLogic System Manager Software, a company executive discovered a major discrepancy between system manager reported data and the utility bill in regards to power factor. Further investigation revealed an uncalibrated utility meter resulting in a $250K credit for past power factor penalty charges.

A PowerLogic power monitoring and control system that was installed and tested at Helen Hayes Hospital in West Haverstraw, NY helps the hospital monitor and test their 1600KW generator. During an outage, the PowerLogic system monitors generation, sheds load to avoid overloading, and re-loads as generation recovers. The system also monitors essential vital signs of the hospital's entire electrical system, and records information necessary to help document JCAHO compliance during generator testing.

A petroleum refinery was experiencing unexplained periodic trips of five large synchronous compressor motors. Each trip resulted in approximately $150,000 in costs due to production losses and Environmental Protection Agency (EPA) fines. After installing a Square D PowerLogic system, the refinery personnel were able to ascertain the cause of the compressor trips and the problem was corrected.

A global supplier of computing and imaging solutions, facing forced utility cutbacks needed a means to quickly shed non-essential electrical loads to avoid a total shutdown. By implementing a system that could shed 15% of the total connected electrical load, within 15 minutes after receiving a call from their local utility, forced outages could be avoided and thus preserve critical power needs.

Concessionaires at Giants Stadium began adding additional electrical equipment, although the electricity cost formula for concessions and suites remained unchanged. It was apparent the stadium was losing out on reimbursable electricity usage. The stadium's power system had four major needs: * Submeter for accurate billing to concessionaires (40) and luxury suites (72) * Monitor quality of power and harmonics, to avoid disruptions; * Estimate future usage and loading * Centralize power management to monitor and report both real-time events and historical usage data.
