Due to the large number of power transformers (ETs) in the distribution system, there is a need for a relatively simple representation of the status of each unit in order to more easily determine where and how to allocate the budget for preventive and corrective maintenance.
In recent years, the concept of the transformer health index (HI) as an integral part of resource management was adopted for the condition assessment and ranking of ETs.
HI algorithms take different forms and can be determined based on a large number of specific parameters.
However, the main problem in HI methodology or any modern diagnostic technique is the existence of regular measurements and inspections and accurate test results.
The paper proposes a solution in the form of the upgraded HI and the novel methodology for ET ranking including the value of available information to describe ET current state.
The confidence to the measurement results is calculated using evidential reasoning (ER) algorithm based on Dempster–Shafer theory.
The contribution to the ER methodology is the calculation of the initial degrees of belief using Markov chains.
The aging process of an ET and transition probabilities from state to state are modelled using the statistical data for the population of 300 ETs and 20 years monitoring data.
The proposed methodology is tested on the real data for 110/35 kV transformer, and in the second case, compared to the sample of 30 110/x kV transformers with traditional HI calculation.
