Picking the right motor condition monitoring system

A motor condition monitoring system is integral to sustainably maintain energy savings and extending motor life expectancy. A 100-hp motor/load consumes 795,118 kWh of energy in a year at 85% efficiency. At 95%, the same motor uses only 691,579 kWh. That’s $48,411 in annual savings at $0.07 per kWh.
