DIAGNOSTIC METHOD OF TECHNICAL CONDITION OF HIGH-VOLTAGE EQUIPMENT OF OPEN DISTRIBUTION DEVICES Russian patent published in 2020 - IPC G01R31/00 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment and can be used for diagnostics of technical condition of high-voltage equipment of open distribution devices (ODD), for example, 110 kV ODD. First, sets of standard images of defects of equipment are made, category of technical condition of equipment is assigned depending on defects. Thermal imaging and ultraviolet monitoring of the equipment is carried out at certain intervals, comparing the obtained images with the reference ones using the machine learning algorithm, determining the actual category of technical state of the equipment units. For oil-filled equipment, if necessary, constant thermal imaging control is also carried out by comparing obtained images with reference ones and monitoring of partial discharges in internal insulation, the results of which are taken into account additionally.

EFFECT: high reliability of diagnosis results.
