  • Field drying of transformer insulation | TD Guardian

    Best industry practice is to regasket the unit approximately every 12-15 years. This is an ideal time to remove the insulation moisture in excess of 0.5% to effectivelyresetand slow the aging process. It is common and acceptable to allow an insulation moisture content of 0.65% for older transformers.
