Even new oil contains moisture that effects if performance. For example the moisture of new oil can be 40 PPM giving an electric strength of 30kV. Purified/Filtered oil can exceed that to significantly below 10 PPM and resulting in electric strength of 60Kv, if purified by our double stage vacuum oil filtration machine, the moisture content can be reduced down to 5PPM and the dielectric strenght can be increased upto more than 65 ~ 75kV. Filtration is also cheaper for the customer and more so when the transformer is filtered live and thereby having no impact to the customer's productivity.
