The disappointment orbreakdown of numerous transformers or comparative hardware can bestraightforwardly ascribed to the absence of appropriate control of the degreeof dampness entering the hardware. It is fundamental, accordingly, that anexceptionally low level of moistness is kept up noticeable all around space inthe highest point of the conservator tank to keep away from crumbling of theprotecting properties of the cooling medium.
Transformerbreathers give a monetary andproductive methods for controling the degree of dampness entering theconservator tank during the change in volume of the cooling medium as well asairspace brought about by temperature changes. Be that as it may, with anotherdampness content detail of oil being kept at under 35 ppm dampness (ASTM D-1533test technique), better desiccant than silica gel is required. ZEOZORB transformerbreathers surpass the ASTM D-1533 testing particulars and out perform silicagel breathers by more than 75% at normal working temperatures 77°F.
