Abstract :
Describes the VersaPac system, explains some potential problems with the system as identified by actual end users, and explains one successful retrofit that solves these inherent problems as requested by customers. The potential problems solved by the retrofitted VersaPac replacement include preventing contaminant tracking between the conductor and ground, allowing easy winding reconnect, and eliminating repeated purchase of VersaPac kits and extended lead times. This particular design has been installed and incorporated into several multi-thousand-horsepower motors in a variety of applications. In all cases, there have been no adverse effects of the conversion
