Degree of drying is directly affect insulation and other specifications of transformer. Therefore, drying insulation systems is the firstly factor to extending transformer life.After drying transformer which be affected by bump, somethings need to do firstly:1) whether exposed time in air is over ti

Millions of transformers are in use today, connecting homes and businesses with needed electricity. Though benign in appearance, the inside of a transformer requires periodic maintenance of its internal oil, through heating and filtration.  Identification A transformer uses

States of Coexistence Next to particlates contamination,moisture is the second-most-destructive contaminant found in machinery. Water can exist in oil in the following three states: Dissolved Contrary to what I was taught, oil and water do blend. The amount of water dissolving into the oil depends u
