Reliability theory and applications to risk analysis of power components and systems

The performance of engineering systems is not deterministic but rather controlled by the uncertainties in the variables affecting that performance. The evaluation of the probability of non-performance can be carried out implementing methods of reliability theory. This work presents a brief discussion of these methods and their applications to four problems relevant to risk analysis of power components and systems: transmission towers, pole distribution lines, the calibration of factored equations for performance-based design, and the reliability updating of existing structures under change of service conditions.
