Testing practices for the AC breakdown voltage testing of insulation liquids

Abstract

It should be pointed out that the dielectric strength of liquids as tested in accordance with current practices to some extent is determined by equipment parameters and not by the sample properties only. Therefore, it is desirable to continue efforts to refine and unify the standard practices to obtain more representative and reproducible test results. What is not always fully recognized is the influence of the test procedure itself and of the test equipment design and characteristics.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
