A method of manufacturing ceramic tape includes a step of directing a tape of partially-sintered ceramic into a furnace. The tape is partially-sintered such that grains of the ceramic are fused to one another yet the tape still includes at least 10% porosity by volume, where the porosity refers to volume of the tape unoccupied by the ceramic. The method further includes steps of conveying the tape through the furnace and further sintering the tape as the tape is conveyed through the furnace. The porosity of the tape decreases during the further sintering step.

Disclosed are a transformer system and a control method of an air-drying device thereof. The air-drying device has a desiccant material stored therein and is connected to a transformer for removing water from an airflow entering the transformer. The control method includes the following steps. The first step is detecting a weight of the desiccant material. The next step is determining whether the weight of the desiccant material reaches a first predetermined weight. The next step is determining whether the transformer is in an air inflow state or an air outflow state, and is conducted when the weight of the desiccant material reaches a first predetermined weight. The last step is heating the desiccant material, and is conducted when the transformer is the air outflow state. Therefore, the lifetime of the transformer can be remarkably extended.
