Residual Life Assessment

The methods so developed are grouped under Residual Life Assessment (RLA) techniques. The potential of such method is tremendous and their advantages are so several in which utilities cannot ignore their significance in the present scenario.

The main objective of RLA is to determine the condition of a set of equipment (example for, transformers) in order to identify the most vulnerable component/equipment. It is based on the evaluation; utilities can develop a strategic replacement plan for a particular population of equipment. The aim should be to maximize the availability and utilization by avoiding unexpected failures and at the same time minimizing risk. Strategies for life assessment are quite complex and involve many aspects (both user-oriented and manufacturer-oriented).
