Abstract
This paper presents a survey of positive pre-breakdown and breakdown currents in transformer mineral oil submitted to 50 Hz alternating voltage. The streamer positive currents are classified according to their possibility to lead towards breakdown. The data constituting the current vectors are collected in real time and smoothed by the use of arithmetic and geometric averages in order to serve as a fast and reliable diagnosis element.
