FIELD: electricity.
SUBSTANCE: invention suggests control method of technical state for components of high voltage equipment (HVE). The method lies in registration and spectrum analysis of own electromagnetic emission for HVE with monitoring of electromagnetic emission spectra. Based on the registered information the aggregate of numerical values is formed for quantity criteria, which allow assessment of HVE technical state. Spectra registration is made in narrow data frequency subranges. The closest regions of own electromagnetic emission spectra are appointed as narrow data frequency subranges, own electromagnetic emission frequencies are determined by an experiment or calculation.
EFFECT: improving objectiveness of technical state determination for high-voltage transformer equipment.
