METHOD OF CONTROL OVER INTEGRITY OF CURRENT CONDUCTING COAT ON DIELECTRIC MATERIAL Russian patent published in 2014 - IPC G01B7/02 

FIELD: instrumentation.

SUBSTANCE: proposed method comprises placing the flat electrode with clearance, measuring capacitance between said flat electrode and current conducting coat surface, displacing said electrode and comparing said capacitances. Note here that said flat electrode is placed on moving electric drive connected with recorder. Said flat electrode is made reciprocating equidistant from current conducting coat surface while said surface is displaced perpendicular to flat electrode motion. Obtained capacitance is compared with reference value. In case recorded values differs from reference one, flaw is considered to occur at current conducting coat.

EFFECT: expanded operating performances, lower labor input.
