Portable test platform for evaluating voltage dip immunity of industrial robots and components in the automotive industry

Abstract

Power quality disturbances like voltage sags and harmonics are an important cause of many ill effects and economic losses in industrial productive processes. Among others problems, production down times, equipment malfunctions and/or destruction of devices and even quality defects in final products can be originated by voltage dips. Power quality surveys and electromechanical device testing are previous steps for achieving an effective mitigation solution. This paper discusses a power quality survey conducted in an automotive company. In addition, a portable test platform for evaluating voltage dip immunity of industrial robots and components is presented. The results obtained from this survey and the immunity test may be useful for improving the power quality of this type of installation [3,4,6].
