METHOD FOR DETERMINING QUALITY OF RUBBER INSULATION OF CABLES Russian patent published in 2017 - IPC G01R31/12 

FIELD: electricity.

SUBSTANCE: cable track segment is selected for analyzing the hardness of the hose insulation and the core insulation. Measurements of hardness H in the amount of 25-30 are carried out in the selected segment. Hardness of the hose insulation H_{I h.i.} and hardness of the core insulation H_{I c.i.} are measured by analyzing the sampling data from n=25-30 measurements on the analyzed segment of the cable track. Then, the data are processed mathematically by calculation.

EFFECT: method allows to determine the quality directly during the cable operation.
