This paper presents the results of a literature search for publications containing failure rates and repair times, based on operational experience, for distribution system components that are critical to the reliability of a distribution system. Furthermore, component failure rates found are compared with the conclusions drawn from a previously conducted literature search.

System lifespan modeling becomes more complicated when an external event causes the succession of failure in 2 or more system components. Models that don’t consider this common cause failure cause the wrong estimation of system reliability. Let us assume that there are data composed of numbers of successive failures in i, i = 1, ... , n out of n components of system. Data having these character...

Unscheduled boiler outages in process industries are a major problem resulting not only in expensive emergency repairs, but also loss of production. This paper draws on the experience of the author's company relating to common failures of pressure parts of boilers. The paper identifies the most common types of pressure part failure and the metallurgical mechanism involved. With a knowledge of t...

ureteral obstruction is relatively common after renal transplantation. a rare cause is the inguinal herniation of the transplant ureter. we report a case of late allograft renal transplant failure due to ureteral herniation as well as ureterovesical junction stenosis.
