Mineral oil for example degrades quickly after absorbing only a small amount of water and moisture in the fluid will break down cellulose often used for insulation. A fluid, in which shear stress is more than the yield value and shear stress to proportional to the rate of shear strain, is known as real plastic fluid. For example, one of the most deployed liquid cooling technologies, “cold plate” or “direct to chip” (D2C), does not typically use dielectric fluid, although technically possible. ANALYSES AND CHECKED POINTS (EXAMPLES) The dielectric fluid analysis measures several indicators which, according to their severities, reveal various types of anomalies (electric and thermal defects, premature ageing, loss of insulating capacity, etc. ). 2.
