Moisture equilibrium in transformer insulation systems: Mirage or reality? Part 2

Sa？etak 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 discusses the moisture cloud algorithm, which reveals the value water in oil measurement has in predicting the amount of water available for drying out, determining the safety margin of the insulation dielectric strength, assessing the residual water in new units undergoing temperature rise test, and in reliably ranking transformers across the fleet in terms of water state
