Abstract :
This paper investigates the effects of electrical disturbances on a computer system consisting of PCs interconnected together with data cables-a PC LAN. The computer system was subjected to the following three types of electrical disturbances: power disturbances from the utility; local disturbances from nearby end-use devices; and RFI from industrial equipment. Test results indicate that a well configured PC LAN is quite immune to most utility power disturbances, but some local disturbances, especially RFI, can degrade the performance of the system considerably. Test results also give important hints towards investigating power quality problems related to computer loads
