The power transformer is one of the most critical assets in power systems; therefore,
planning and optimizing the economic investment for its replacement is crucial for the …

In every electric power system, power transformers (PT) play a critical role. Under ideal
circumstances, PT should receive the utmost care to maintain the highest operative …

These two-part paper series aim to optimize the rates of inspection-based maintenance or
routine-test on power system equipment. Part I introduced a novel probabilistic model using …

Assessment of overhead transmission lines is a crucial task in the asset management of
electric power infrastructures. Any assets have different life spans and require proper …

In this paper, we apply the Failure Modes, Effects, and Criticality Analysis (FMECA)
approach to the criticality and risk analysis of the efficiency, safety/reliability, environment …

Abstract System reliability and life-cycle cost are significantly influenced by preventive
maintenance (PM). PM is commonly classified into two categories: time-based maintenance …

In the process of power transformer risk assessment, the loss degree index is difficult to
accurately quantify due to the influence of uncertain factors, leading to the deviation of risk …

Abstract System reliability and life-cycle cost are significantly influenced by preventive
maintenance (PM). PM is commonly classified into two categories: time-based maintenance …

Regular evaluation and risk assessment of the technical condition of power transformers is
very important. It is known that good condition state guarantee system's reliability. Various …

This paper proposes a program development for condition and importance assessment of
high voltage transmission line in Thailand. The condition criteria consist of age, stress …
