Rural power quality

A detailed statistical analysis and discussion of the quality of power monitored at two farm sites in the Province of Alberta, Canada, are presented. The origins, causes, and types of power system disturbances and their unique patterns of occurrence at each site are presented and discussed in detail. An existing methodology to assess the possible impact on the life and performance of electrical and electronic equipment subjected to the power supply anomalies monitored at each site is presented and illustrated. The power profile of each site was superimposed onto the CBEMA (Computer Business Equipment Manufacturers' Association) curves which characterize regions of trouble-free computer operation and regions of problematic operation and possible equipment damage. The method illustrated enables an assessment of the probable operation of newly introduced sensitive controls and computer equipment into an existing rural electrical environment.<>
