title = "Development of an Experimental Setup to Study the Bubble Formation of Transformer Insulation Systems",
abstract = "Bubbles in transformers caused by overloading could weaken the insulation system and lead to dielectric failures. The bubble formation process has been studied for many decades and results have led to the hot-spot temperature constraint of 140 °C for 2% of water content in cellulose. This paper utilizes a small-scale test system to observe the randomness in the bubble formation process and hence to study the suitability of such a single temperature-water content in paper relationship to describe bubble formation. Multiple tests conducted with the same initial water content in paper have shown that bubble inception time and temperature can vary under same initial conditions.",
