Reliable diagnostics of electrical equipment in power systems requires analysing sets of mutually related parameters rather than isolated measurements. This paper proposes a structured methodology for selecting, grouping, and analysing diagnostic parameter sets for electrical equipment (e.g., generators, transformers, motors, switchgear). The approach combines: (1) an initial classification of candidate parameters by physical domain; (2) multi-criteria scoring based on informativeness, measurability, sensitivity, correlation, and stability; (3) statistical analysis (correlation analysis and principal component analysis) to reduce dimensionality; and (4) clustering and expert judgement to form meaningful parameter groups. The methodology is illustrated on a power transformer case, including example tables and graphical representations of parameter rankings and dimension reduction. The proposed approach yields compact, informative parameter sets and logically structured parameter groups, which form a robust basis for subsequent diagnostic modelling (statistical, AI-based, or hybrid).
