Electrical Safety Related Isolation on Industrial Machines with Multiple Entry Points

Abstract

In industrial machine, there is often more than one entry point that might be used during the operation and maintenance functions. Typically, the lockout/tag-out procedures prior to entering the machine have been done using series-connected conventional load-break disconnect switches. Unfortunately, the required verification is problematic for applications requiring only one disconnect switch and is almost impossible when more than one disconnects switch is applied. Industrial equipment design must include safe methods to allow access for either maintenance or operational intervention. Although the overall safety elements of the industrial equipment design efforts are predominately a part of the mechanical machine’s design, often, the motive forces that must be considered are directly or indirectly associated with the control of electrical energy. Considerations in selecting safe methods for intervention are those associated with ease of use (human factors) and those associated with equipment reliability. This Project new multiple entry point method is proposed industrial machines for Industrial Electrical Safety System.
