Some Problems in the Testing of Transformer Oil of Petroleum Origin for Dielectric Breakdown Strength

CODEN: JTEVAB

Abstract

A description of the process of dielectric breakdown in insulating oils is presented. The technological changes which made necessary the development of ASTM Standard D 1816-67 as an alternative to D 877-67 are described. The emphasis is on practical considerations which influence the variability of the test results and the differing responses of the two methods to these factors. Suggestions are made as to possible modifications in procedure which might reduce the variability of test results without detracting from their practical applicability.
