%0 Journal Article %T Water in transformers: Moisture equilibrium in transformer insulation systems: Mirage or reality? Part 1 %A Roizman %A Oleg %J - %D 2019 %X Sa£żetak In the operating transformer water is always in transition, either moving within cellulose insulation or migrating from paper to oil and versa visa. This article introduces a methodology where we use an equilibrium chart for an assessment of a dynamic process which may not reach an equilibrium and still give us a good sense of moisture state in the oil/paper system %K water %K transformer %K moisture %K insulation %U https://hrcak.srce.hr/index.php?show=clanak&id_clanak_jezik=319420
