Abstract
Изобретение позвол ет повысить производительность труда, достоверность обнаружени дефектов и упростить способ. Дл этого измерение электропроводности производ т непрерывно и одновременно с абразивной обработкой. Путь сошлифовывани материала образца в плоскости, перпендикул рной плоскост м обкладок конденсатора. Сопротивление изол ции образца практически не измен етс , если стачиваемые объемы не содержат дефектов изол ции. При вскрытии в процессе шлифовани дефекта сопротивление изол ции образца увеличиваетс , что фиксируетс прибором, к которому при помощи электродов подключен исследуемый конденсатор. После этого абразивную обработку конденсатора прекращают.The invention makes it possible to increase labor productivity, reliability of defect detection and to simplify the method. To do this, the measurement of electrical conductivity is carried out continuously and simultaneously with abrasive processing. The path of grinding the sample material in a plane perpendicular to the planes of the capacitor plates. The insulation resistance of the sample remains almost unchanged if the volumes being ground do not contain insulation defects. When the defect is opened during the grinding process, the insulation resistance of the sample increases, which is fixed by the device to which the capacitor under study is connected by means of electrodes. After this, the abrasive processing of the condenser is stopped.

When the defect is opened during the grinding process, the resistance of the sample insulation increases abruptly, which is recorded by a recording device. Thereafter, the abrasive treatment of the condenser under study is stopped and the sample is transferred for visual inspection of the detected defect under a microscope and for physico-chemical studies.
