Abstract

This article reviews the issues of allowances which have been accepted within the methods of liquid insulation technical status control in oil-filled high-voltage electric equipment based on nonlinear parametrical interaction of the acoustic vibrations. The updating of predeveloped method was proposed by the residence time of gas microinclusions in transformer oil and solubility of gas inclusions researching.

Keywords

Isolation of oil-filled equipment, partial discharges, gas bubbles.
