" ... Electricity now powers devices of amazing technological sophistication, from lightning-fast desktop computers to flat screen TVs. But our means of getting power from the plant to the plug hasn't changed much since the early 20th century. "

IEEE Xplore - Abstract Page: "Thereby, the results can provide an early forecasting for equipment fault and scientific evidences for equipment maintenance and out of service, which are caused by equipment aging."

" ... Models have been published addressing the issue of the calculation of the remaining life, future failure rates and the probability of failure of power equipment. ... " (HERE)
" ... Older equipment have higher failure rates, leading to customer interruption rates affecting the economy and society; also, older assets and facilities lead to higher inspection maintenance costs and further repair/restoration costs. ... " (HERE)
" ... Aging transmission and distribution infrastructure poses increasing obstacles for the power industry. Industry-wide run-to-failure policies have left large portions of utilities' transmission and distribution infrastructure rapidly approaching or exceeding expected service lifetimes. ... " (HERE)
" ... At 3:05 p.m. on Aug. 14, 2003, a 345-kV transmission line in northern Ohio began to sag. This happens commonly, especially during hot summer days, when the demand for power created by all those air conditioners can cause power lines to slacken.
Energy, which was responsible for powering northern Ohio, should have detected the loss of that first line, but its energy management system wasn't working at the time (the company didn't know that). Higher up, the Midwest Independent System Operator's state estimator, which helps ensure reliability for several utility companies in the region, had just been taken down for troubleshooting that day, and wasn't fully back online yet, so operators were unable to get an accurate, real-time picture of what was happening to the grid. ...
