Abstract

The drying process for upgrading transformer insulating liquids using zeolite was described. The drying efficiency of high-voltage transformers depended on process duration, environmental impact, connections between the transformer and the drying units, voltage rating and the capacity of the drying unit. The process involved the use of filter to purify the liquid which reduced source for partial discharges (PD) or breakdowns. The zeolite sensor determined the actual status of the zeolite filter by measuring the variation in conductivity or permittivity of a sensor filled with the same material.
