METHOD OF DETECTING DEFECTS IN TIGHTNESS OF ELECTRIC INSULATION Russian patent published in 2005 - IPC

Abstract RU 2250473 C1

FIELD: electric engineering; measurement technology.

SUBSTANCE: method can be used for inspection of integrity of electric insulation. According to the method item is placed into transparent chamber filled with special liquid and is subject to physical action. Tightness of item is judged from bubbles of gas. Physical action concludes in applying physical load during 10-600 seconds and electrical load is set within range of 500-2500 V. Transformer oil is used as technical oil with water content of 0,01-0,1%.

EFFECT: nondestructive detection of defects in tightness.
