CONTROL METHOD OF TECHNICAL STATE OF ELECTRIC POWER EQUIPMENT Russian patent published in 2011 - IPC G01R31/00 

FIELD: electricity.

SUBSTANCE: invention refers to noise diagnostics methods of electric power equipment (EPE) and is designed for erection of industrial information-measuring built-in control complexes of such equipment. In control method of EPE technical state the complete defectiveness of diagnosed equipment under voltage is determined based on preliminarily obtained data on defectivenesses regarding separate voltage inputs in this equipment, and defectiveness regarding certain voltage input in diagnosed equipment is determined based on comparison in equivalent conditions of measured power spectra of flicker components of noise currents in wires of control branches with the corresponding voltage inputs for single-type diagnosed and reference equipment.

EFFECT: increasing sensitivity and improving reliability of defectiveness diagnostics.
