Moisture is one of the greatest threats to a power transformer. It rarely manifests itself through a sudden failure or an immediate protection trip; instead, it accumulates gradually, year after year, until one day it reveals itself through reduced insulation dielectric strength, shortened service life, or, in the worst case, an internal short circuit. WhyRead More
Dry oil does not always mean dry winding insulation. Moisture can remain trapped in cellulose insulation for weeks, even after the oil has already reached acceptable moisture levels.
