Abstract: Today electronic devices require a power supply without any variation or disturbance. Nevertheless, electrical variations presented in power lines are more frequent and powerful. The consequences of poor power quality are reflected in the lifetime and performance of electronic devices. Thus, in this study, an FMEA is presented to know which electrical variation has more effect on the reliability of electronic devices. The analysis was performed following the classification of electrical disturbances which consider the waveform of the disturbance. The results of the FMEA showed that electrical harmonics have more influence to harm an electronic device. In addition, a reliability analysis is performed in this study to measure the effects of the electrical variation via mean time to failure. The electronic product selected was a laptop computer. The results of the reliability analysis showed that laptop computer reduced its lifetime in around 4800 h under the electrical variation selected. [ABSTRACT FROM AUTHOR]
