ISODRY ® Series Online Transformer Insulation Drying Systems
HERING prides itself on the number of transformer treatment options that it offers its business partners. The ISODRY® Series is focused specifically on moisture removal, particularly from the paper insulation in the transformer core. The harmful effect of water on the transformer dielectric strength is generally well-known and appreciated and there are a number of solutions that address that. The ISODRY® Series, and its vacuum based complement, TIDO, reduce aging effects on the cellulose insulation by continuously removing water – unattended.
