CONTROL METHOD OF TECHNICAL STATE OF ELECTRIC POWER EQUIPMENT Russian patent published in 2013 - IPC G01R31/00 

FIELD: electrical engineering.

SUBSTANCE: invention refers to noise diagnostics methods of electric power equipment (EPE) and is designed for erection of industrial information-measuring complexes for technical control of such equipment condition. Complete defectiveness of voltage-bearing equipment is determined based on data obtained on defectiveness of individual structural elements positioned inside and outside such equipment metal housing. Defectiveness of a specific structural element, external (voltage input) or internal (voltage regulator, inductance coil, equipment metal housing etc), is determined based on comparison of measured and equivalent conditions of spectral current densities within wires of the control branch circuits of the corresponding voltage inputs for similar diagnosed and reference equipment at selected frequencies determined through calculations and experiments.

EFFECT: increasing sensitivity and improving deepness and reliability of defectiveness diagnostics.
