This paper analyzes the existing regulatory indicators of the technical condition of power transformers. Causal relationships between measurable parameters and defects in the transformer have been studied to identify vulnerabilities and likely scenarios for an emergency. The technical condition of the transformer was assessed using the method of pairing comparisons. The probability of trouble-free operation of functional nodes and transformer in general has been determined. The impact on all transformer systems in determining its lifespan of congestion and short-circuit currents by introducing congestion ratios has been taken into account.
