Momentary Outage Causes <br /> The ability to track momentary outages can be difficult or unavailable on some systems, but due to the <br /> hazard they pose for electronic equipment, it is important to track and analyze momentary causes. In this <br /> section, we evaluate common causes of momentary outages for your utility, region and customer size <br /> class as well as common causes for all utilities that use the eReliability Tracker. Please note that only <br /> outages lasting less than five minutes are classified as momentary, as defined by IEEE 1366. <br /> Figure 11 <br /> Top five customer-weighted occurrence rates for common causes of momentary outages for all <br /> utilities that use the eReliability Tracker Service 2 <br /> 0.14 - 0.1321 <br /> 0.12 - <br /> en <br /> °'• 0.1 - 0.0904 <br /> 0.0812 <br /> 0.08 - 0.0633 0.0598 <br /> 0.06 - <br /> • 0.04 - <br /> O 0.02 - <br /> 0 1 1 I 1 <br /> Utility Maintenance and Unknown Equipment Replacement Failure of Greater Equipment <br /> Repairs Transmission <br /> Outage Cause Types <br /> Figure 12 <br /> Top five customer-weighted causes of momentary outages for your utility2'3 <br /> 0.1 <br /> 0.0819 0.0819 <br /> a, 0.08 <br /> a) <br /> ▪ 0.06 <br /> co <br /> ;v 0.04 <br /> O 0.02 <br /> O 0 0 0 <br /> 0 <br /> Electrical Failure Vehicle Accident None None None <br /> Outage Cause Types <br /> 3 <br /> If your utility has less than eight momentary outages recorded in the eReliability Tracker,this graph will be blank. <br /> 14 <br /> 94 <br />
